After all of the thermal resistance values have been established, the heat transferred               can be calculated for the raceway with the three hour barrier.
The thermal resistance values will be determined based on test data and physical properties as follows:
Since the heat is a function of the current squared,             the ampacity correction factor   (ACF) will   be determined by the following relationship.

4.3 Heat   transfer through the sides of cable tray will be assumed to be zero. This will reduce the heat transfer equation for tray to a one dimensional heat transfer equation. As the tested cable tray is relatively wide ,24", this is expected to be a good approximation for all cable tray.
Heat transfer through the sides of cable tray will be assumed to be zero.
4.4 One   hour Thermo-Lag fire barrier will be assumed           to be at the minimum thickness of 1/2" (I/4" for overlay       where used).     This thickness   will provide   a conservative value when calculating the     R value for the gap between the raceway and the barrier.
This will reduce the heat transfer equation for tray to a one dimensional heat transfer equation.
4.5 Three hour Thermo-Lag fire barrier will be assumed to be at the nominal thickness in accordance with the manufacture's tolerance, l-l/4 inches. This thickness'will provide a conservative result when calculating the heat transferred with the three hour barrier, as the value of the initial I hour wrap was minimized.               It was judged to be unrealistically conservative to go to the maximum thickness tolerance of 1.5 inches.
As the tested cable tray is relatively wide,24", this is expected to be a good approximation for all cable tray.
4.6 Raceway     is made   of rigid steel, magnetic material, which is typical for               power plant installations.
One hour Thermo-Lag fire barrier will be assumed to be at the minimum thickness of 1/2" (I/4" for overlay where used).
Banked   conduit which is banked in a single plane can be assumed to be equivalent to cable tray. Both configurations involve a cable mass arranged in a shallow rectangular section.
This thickness will provide a conservative value when calculating the R value for the gap between the raceway and the barrier.

The current in aay given system was driven to a level high enough to bring the conductor to 90'C as quickly as possible by increasiag the'output signal of the process controller via keypad commands.             As the conductor temperature approached     90'C,   the current level was reduced aad the test article was given time to respond to current changes before another adjustment was made to the current. During this time period, the controller was turned to "automatic" control and the "process variable set point" (the voltage output from the current transformer that represents the current level at which the controller will maintain the system) was adjusted to the same value as the displayed process variable (the controller varies its output ia order the maintain the process variable at the level indicated by the set point).

During this time period, the controller was turned to "automatic" control and the "process variable set point" (the voltage output from the current transformer that represents the current level at which the controller will maintain the system) was adjusted to the same value as the displayed process variable (the controller varies its output in order the maintain the process variable at the level indicated by the set point).
This process of adjusting the controller output (and the control variable set point) and waiting for the system to stabilize (about 1/2 hour to about 2 hours, depending upon the nature of the system) was continued until the temperature parameters of the test article were within the specified limits. The controller was allowed to operate the system for a minimum of three hours.
If, at the end of three hours, the system was still within the bounds of all specifications, a final current and voltage measurement were taken and the system was deemed
.to be in equilibrium.
All final current measurements were performed using ammeters supplied and calibrated by Texas Utilities Electric. These ammeter used were manufactured by James Biddle Co. and identified as Biddle Instruments Digital Clamp-On RMS Volt-Aauneter, Cat. No. 278001 (TU Electric ID No. IC-1029 and IC-1030).

3.0 Methodology

THERI'AO-LAG CONDUIT CABLE Ri Rt Rs Rg Heat transfer will be calculated per foot of raceway length in accordance with the following relationship:

q (Tc-Ta) / (Ri + Rg + Rt + Rs) q Tc Ta Ri Rg Rt Rs Rate of heat transfer from raceway Temperature of conductor (90'C/194'F)

Ambient temperature (40'C/104'F)

Thermal resistance of all items within the raceway including the raceway itself Thermal resistance of the air gap between the raceway and the fire barrier material Thermal resistance of the fire barrier material Thermal resistance at the surface of the protected or unprotected raceway The heat transferred from the raceway under steady state conditions is essentially equal to the I'R losses within the conductors.

These heat values can be determined from the test data based on the measured current and size of conductor used.

Tc and Ta are fixed test parameters with values which are listed above.

The thermal resistance values will be determined based on test data and physical properties as follows:

Ri will be calculated from the test data for raceway without fire barrier Rg will be calculated from the test data for raceway with a I hour barrier Rt will be calculated based on the known thermal conductivity (k) for The~mn-Lag Rs will be based un known physical properties considering convection arid radiation heat transfer.

After all of the thermal resistance values have been established, the heat transferred can be calculated for the raceway with the three hour barrier.

Since the heat is a function of the current squared, the ampacity correction factor (ACF) will be determined by the following relationship.

ACF I/I V(q,~q where the subscript p refers to the protected raceway 4.2 4.3 4.4 4.5 4.6 Assumptions/Bases The effect of inductive losses in the raceway and cable sheath will be negligible with respect to applying the test data to the Turkey Point and St.

Lucie configurations, Surface emittance for cable,

raceway, and Thermo-Lag will be assumed to be equal to 0.9.

Note that a high emittance value will reduce the thermal resistance at the surface having an overall effect of maximizing the ampacity de-rating.

Heat transfer through the sides of cable tray will be assumed to be zero.

This will reduce the heat transfer equation for tray to a one dimensional heat transfer equation.

As the tested cable tray is relatively wide,24", this is expected to be a good approximation for all cable tray.

One hour Thermo-Lag fire barrier will be assumed to be at the minimum thickness of 1/2" (I/4" for overlay where used).

This thickness will provide a conservative value when calculating the R value for the gap between the raceway and the barrier.

Three hour Thermo-Lag fire barrier will be assumed to be at the nominal thickness in accordance with the manufacture's tolerance, l-l/4 inches.

This thickness'will provide a

conservative result when calculating the heat transferred with the three hour barrier, as the value of the initial I hour wrap was minimized.

It was judged to be unrealistically conservative to go to the maximum thickness tolerance of 1.5 inches.

Raceway is made of rigid steel, magnetic

material, which is typical for power plant installations.

Banked conduit which is banked in a single plane can be assumed to be equivalent to cable tray.

Both configurations involve a cable mass arranged in a shallow rectangular section.

Both configurations involve an air gap between the cables and the fire barrier material.

Considering that the geometry of these areas is not

changed, this approximation is reasonable for the purpose of extrapolating the thermal resistance from raceway with 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> wrap to raceway with 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> wrap.

Conduit diameters are obtained from Reference 2.5.

TH This value is the thermolag thickness.

For each raceway size a

thickness representing no wrap, 1 Hr wrap, and 3 Hr wrap is entered.

ODT This is the outside diameter of the raceway with any wrap calculated from the 00 and TH.

For cable tray OD is not calculated because it will always be equal to W,

Note that for raceway both the top and bottom areas are included.

Area is calculated on the basis of a one foot length of raceway.

Ri Inside thermal resistance as defined above.

The value is calculated from the test data with no wrap in accordance with the following formula.

The Ri value calculated is then used for the cases with 1 Hr and 3 Hr wrap.

Note that there is no Rg and Rt for this case.

of 15 A Fire Protective Envelope protects electrical components from the eQ'ects of fire.

In doing sc, it vriQ reduce the inQow of energy into the system and maintain the internal temperature below maximum limits. These limits will ensure that the cable systems remain functional during a fire, and allow operators to maintain control of systems required for fire safe shutdown.

The addition of a Are. rotective Envelope on a cable system willnot only protect the contained cable from elevated temperatures associated with a fire, but will impede the heat dissipation associated with cable operation.

The evaluation described herein will yield aa accurate and realistic value for the ampacity deratiag of cables when a Fire Protective Envelope is iastaQed on the cable system.

This entire test prolpmn was performed in accordance with Texas Utilities Electric TEST PLAN, Rev. 4, which has been included in Appendix B.

The specific details ofthis project wiQ be found in that document.

TEAENCLOSURE The ampacity test enclosure was constructed of steel stud waQs and ceiling with a minunum of I in. of polystyrene insulatioa liaing the interior of the room.

The overaQ dimensions of the test enclosure were 20 ft. x 18 &. x 8 ft. An entry door was provided in oae wall and an observation window was placed in an adjacent waQ. The waQ with the observation window was made to be removable to facilitate easier location oftest articles. Four 1.5 kW heaters were disposed about the room to regu1ate ambient conditions.

of l5 assembly) or the instrumented cable was removed from the clad conduit and inserted into a similarly constructed, bare conduit.

THERMOCOUPUK Temperatures on the cable conductors within the conduit and air drop assemblies were measured with Type T, 24 gauge, Copper-Constantan electrically welded thermocouples formed from Copper and Constantan wires of special limits of error (&.5'C)," and covered with TeQon FEY insulation.

Temperatures on the cable conductors within the cable tray assembly were measured with Type K, 24

gauge, Chromel-Alumel electrically welded thermocouples formed from Chromel and Alumel wires of "special limits of error (21.1'C)," and covered with braided fiberglass insulation. Allthermocouple wire was calibrated to &.5'C.

DATAACQUXSZZXONSYSTEM The outputs-of the test article thermocouples and room control thermocouples were monitored by a data acquisition system consisting of a John Fluke Mfg. Co.

Model HELIOS I 2289A Computer Front End, and an Apple Computer Co.

Macintosh Classic microcomputer.

The Computer Front End was connected to the RS422 Serial Interface Port of the Macintosh.

The computer was prograxnmed in Microsoft BASIC to command the HELIOS unit to sample the data input lines, receive and convert data into a digital format, and to manipulate the data for display on screen, the hard copy printout, and saving to hard disk. The computer program determined, and displayed, the average temperatures at each of the three positions on each test article.

The rate of change of temperature for the average of the thermocouples located in the center portion of the test article was.

then calculated.

Allindividual data points and calculated values were saved on hard disk at one minute intervals. A record ofindividual location temperatures, maximum temperatures and rates of change of temperatures was printed at five minute intervals. Alltest data is presented in Appendix F: TEST DATA.

CONTROLSYSTEM The current Qow through the test articles was regulated using process control type devices.

The available voltage for any test control circuit was 208 Vac single phase.

A Silicon Controlled RectIfier (SCR) device (Halmar Robicon Group Model No. 140P-FK2-CL) was used to vaxy the voltage available to the primary side of a step-down transformer between 0 Vac and 208 Vac in proportion to a 4-20 mA control input.

The test article was connected to the secondary side of the step-down transformer.

A proportional-integral-derivative process controller (Honeywell Universal Digital Controller Model No. UDC 3002-0-000-1-00-XXXK) was responsible for generating the '4-20 mA signal fed to the SCR device, based on a voltage feedback loop.

of 15 or 76-102, 1000:5 ratio; input amps:output amps) was fitted to one lead of the test article to monitor the current flow through the conductor.

The output of the current transformer was connected to a current transducer (Flex-Core Model No.

CT5-005A) with a mA to mV converter (Flex-Core Model No. LRB-10000) to produce a 0-10 Vdc signal proportional to 'a 0-150 A or 0-1000 A current span in the sample conductor.

This 0-10 Vdc signal is used as the 'process variable" in the feedback loop to the controller.

In essence, the above circuitry made up a constant-current device, insensitive to line voltage changes.

The current in aay given system was driven to a level high enough to bring the conductor to 90'C as quickly as possible by increasiag the'output signal of the process controller via keypad commands.

As the conductor temperature approached 90'C, the current level was reduced aad the test article was given time to respond to current changes before another adjustment was made to the current.

During this time period, the controller was turned to "automatic" control and the "process variable set point" (the voltage output from the current transformer that represents the current level at which the controller will maintain the system) was adjusted to the same value as the displayed process variable (the controller varies its output ia order the maintain the process variable at the level indicated by the set point).

This process of adjusting the controller output (and the control variab1e set point) and waiting for the system to stabilize (about 1/2 hour to about 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, depending upon the nature of the system) was coatinued until the temperature parameters of the test article were within the specified limits. The coatroller was allowed to operate the system for a muumum of three hours.

If, at the end of three hours, the system was still within the bounds of all specifications, a final current and voltage measurement were taken and the system was deemed

.to be in equilibrium.

s All final current measurements were performed using ammeters suppHed and calibrated by Texas UtiTities Electric. These ammeter used were manufactured by James Biddle Co. and identified as Biddle Iastruments Digital Clamp-On RMS Volt-Ammeter, Cat. No. 278001 (TU Electric ID No. IC-1029 and IC-1030).

Measurements recorded for test items containing 3C/¹10 AWG of 3C/¹6 AWG cable were taken with the ammeter ID No. IC-1030.

Current measurements recorded for test items containing 750 kCMil cable were taken with the ammeter ID No. IC-1029.

Calibration documentation for these devices can be found i' Appeadix G: Quality Assurance.

of 15 A Fire Protective Envelope protects electrical components from the eG'ects of fire.

In doing so, it willreduce the inQow of energy into the system and maintain the internal temperature below maximum limits. These limits will ensure that the cable systems remain functional during a fire, and allow operators to maintain control of systems required for fire safe shutdown..

The addition of a Fire Protective Envelope on a cable system willnot only protect the contained cable from elevated temperatures associated with a fire, but will impede the heat dissipation associated with cable operation.

The evaluation described herein will yield an accurate and realistic value for the ampacity derating of cables when a Fire Protective Envelope is'instaQed on the cable system.

This entire test program was performed in accordance with Texas Utilities Electric TEST PLAN, Rev. 4, which has been included in Appendix B.

The specific details ofthis project willbe found in that document.

The ampacity test enclosure was constructed of steel stud walls and ceiling with a muiimum of 1 in. of polystyrene insulation lining the interior of the room.

The overaQ dimensions of the test enclosure were 20 ft. x 18 R. x 8 R. An entry door was provided in one wall and an observation window was placed in an adjacent waQ. The waQ with the observation window was made to be removable to facilitate easier location oftest articles.

Four 1.5 RW heaters were disposed about the room to regulate ambient conditions.

Two of the heaters were variable from outside of the test enclosure via connection to standard laboratory variable transformers.

Located directly behind each heater was a 24 in. box fan to gently stir the air and more evenly distribute the heat.

A total of nine thermocouples were suspended from the ceiling and positioned in the horizontal plane of the test items, 12 in.

away from various test items to monitor the ambient room temperatures.

Two stanchions were erected to support the test articles.

Each stanchion consisted of a length of 2 in. square steel tubing supported at several points by an A-frame leg.

A length of2 in. x 4 in. wood stud was afBxed to,the top surface of each stanchion.

In the case of all but the 5 in. conduit, the test article with the fire protective system installed was tested first. Once the system had attained equilibrium and all final measurements had been taken, the fire protective barrier was removed from the system (in the case of the air drop assemblies and the cable tray

of 15 assembly) or the instrumented cable was removed from the clad conduit and inserted into a similarly constructed, bare conduit.

TEGWKOCOUPUH Temperatures on the cable conductors within the conduit and air drop assemblies were measured with Type T, 24 gauge, Copper-Constantan electrically welded thermocouples formed from Copper and Constantan wires of "special limits of error (M.5'C)," and covered with TeQon FEY insulation.

Temperatures on the cable conductors within the cable tray assembly were measured with Type K, 24 ga'uge, Chromel-Alumel electrically welded thermocouples formed from Chromel and Alumel wires of "special limits of error (%1.1'C)," and covered with braided fiberglass insulation. Allthermocouple wire was calibrated to &.5 C.

DATAACQUISXHONSYSTEM The outputs-of the test article thermocouples and room control thermocouples were monitored by a data acquisition system consisting of a John Fluke Mfg. Co.

Model HELIOS I 2289A Computer Front End, and an Apple Computer Co.

Macintosh Classic microcomputer.

The Computer Front End was connected to the RS422 Serial Interface Port of the Macintosh. The computer was programmed in MicrosoR BASIC to command the HELIOS unit to sample the data input lines, receive and convert data into a digital format, and to manipulate the data for display on screen, the hard copy printout, and saving to hard disk. The computer program determined, and displayed, the average temperatures at each of the three positions on each test article.

The rate of change of temperature for the average of the thexmocouples located in the center portion of the test article was then calculated.

Allindividual data points and calculated values were saved on hard disk at one minute intervals. A record ofindividual location temperatures, zmuamum temperatures and rates of change of temperatures was printed at Gve minute intervals. Alltest data is presented in Appendix F: TEST DATA.

CORZROL SYBZESX The current Qow through the test articles was regulated using process control type devices.

The available voltage for any test control circuit was 208 Vac single phase.

A Silicon Controlled=Rectifier (SCR) device (Ha1mar Robicon Group Model No. 140P-FK2-CL) was used to vary the voltage available to the primary side of a step-down transformer between 0 Vac and 208 Vac in proportion to a 4-20 mA control input.

The test article was connected to the secondary side of the step-down transformer.

A proportional-integral-derivative process controller (Honeywell Universal Digital ControQer Model No. UDC 3002-0-000-1-00-ZQZ) was responsible for generating the 4-20 mA signal fed to the SCR device, based on a voltage feedback loop. A current transformer (Flex-Core Model No.58-151, 150:5

of 15 or 76-102, 1000:5 ratio; input amps:output amps) was fitted to one lead of the test article to monitor the current flow'hrough the conductor.

The output of the current transformer was connected to a current transducer (Flex-Core Model No.

CT5-005A) with a mA to mV converter (Flex-Core Model No. LRB-10000) to produce a 0-10 Vdc signal proportional to a 0-150 A or 0-1000 Acurrent span in the sample conductor.

This 0-10 Vdc signal is used as the "process variable" in the feedback loop to the controller. 'In essence, the above circuitry made up a constant-curx'ent device, insensitive to line voltage changes.

The current in any given system was driven to a level high enough to bring the conductor to 90'G as quickly as possible by increasing the'output signal of the process controller via keypad commands.

As the conductor temperature approached 90'C, the current level was reduced and the test article was given time to respond to current changes before another adjustment was made to the

'urrent.

During this time period, the controller was turned to "automatic" control and the "process variable set point" (the voltage output from the current transformer that represents the current level at which the controller will maintain the system) was adjusted to the same value as the displayed process variable (the controller varies its output in order the maintain the process variable at the level indicated by the set point).

This process of adjusting the controller output (and the control variable set point) and waiting for the system to stabilize (about 1/2 hour to about 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, depending upon the nature of the system) was continued until the temperature parameters of the test article were within the specified limits. The controller was allowed to operate the system for a minimum of three hours.

If, at the end of three hours, the system was still within the bounds of all specifications, a final current and voltage measurement were taken and the system was deemed

.to be in equilibrium.

All final current measurements were performed using ammeters supplied and calibrated by Texas Utilities Electric. These ammeter used were manufactured by James Biddle Co. and identified as Biddle Instruments Digital Clamp-On RMS Volt-Aauneter, Cat. No. 278001 (TU Electric ID No. IC-1029 and IC-1030).

Measurements recorded for test items containing 3C/¹10 AWG of 3C/¹6 AWG cable were taken with the ammeter ID No. IC-1030.

Current measurements recorded for test items containing 750 kCMilcable were taken with the ammeter ID No. IC-1029.

Calibration documentation for these devices can be found in Appendix G: Quality Assurance.
