Rev. l' SAR-PGDP September 15,1995 Transformers are protected by an electrical relaymg synem which isolates and de-energizes the unit when fauks, overloads, and other abnormal conditions occur. This relaying system is renrhm and is extremely reliable.
1 3.9.1.3 14-kV Distribution Systein
'Ihe 14-kV distribution system is 04 m =4 of five major types of electrical equipment; The transinon bus ductwork 14-kV switchgear
=
14-kV feeder cables
=
Synchronous condensers 14-kV static capacitors e
The transaion bus duct transfers power from the low voltage termmak of the main power transformers to the 14-kV swuchgear. The switchgear then transfers power to the process transformers via 14-kV feeder cables. 'Ibe sysu-os condensers and 14-kV static capacitors are used for power factor improvement and voltage regulation. They are connected to the 14-kV switchgear via electric feeder cables.
3.9.1.3.1 Tr==*lan Bus Ductwork p
The 14-kV power is supplied from the transformers to the switchgear via isolated phase bus duct o== =kg of a metal enclosure cantniaing insulator-suyymW4 conductors. Each phase cr- *-T-follows a separate enclosed path. The porcelain insulators suyymdug each conductor insulates it from its metal enclosure and holds k in a fixed location wahm the enclosure.
The isolated phase bus duct is rated to carry 5,000 amperes confunmusly with w+rature rise not to exceed 50*C over a 40'C ambient temperature. 'Ibe current conda~ine portion unhzes either large copper bars or high caadar +>vay ahwai== The bus duct is rated to withenntf the maximum possible short circuit stress.
'Ibe main current carrymg parts of the bus duct are protected by zones of relaying used to detect fauks wnhm the yswd zone. All metal enclosures of the bus duct are electrically boaded and grounded for personnel safety.
3.9.1.3.2 14-kV Switchgear The 14-kV swhchgear provides the means for disconnecting and protecting electrical equipment.
Each switchgear typically has ten adjacent air-operated circuit breakers (ACB) cubicles, each containing an ACB and interconnecting bus conductors. A common 14-kV bus is connected to each ACB. The switchgear units are of the outdoor metal enclosed station cubical-type, with compressed air-operated circuit breakers. Each unit is camaa~d of various combinations of cubicles. A typical switchgear feeder cubicle conrains an ACB rated at 2,000 amperes with nis y elec:rical bus conductors to receive power from the 14-kV bus and to supply power to process distribution 14-kV feeder cable. Each ACB cubicle 3.9-5
-l SAR-PGDP May 4,1997 Rev.9 contains its air-operated opening and closing mechanism and instrument and current transformers for monitoring the amount of current flowing through the breaker and feeder. In addition, each switchgear I
has two 5,000 ampere-rated breakers to connect the switchgear bus to the 14-kV transition bus from the main and reserve transformers. One cubicle of the switchgear is reserved for the bus potential transformers which are sensing devices for relaying and voltage monitoring. When required, the switchgear also has breakers to connect the switchgear bus to the synchronous condensers and 14-kV static capacitors. Each ACB contains manually operated disconnect switches which, when opened physically, disconnect the ACBs from sources of electrical power and allow routine maintenance to be performed without removal of the entire switchgear from service.
Air-operated circuit breakers are opened to trip compressor motors for the "000" cells. To assure proper operation of the air-operated opening mechanisms for these breakers, a minimum air pressure of 190 psig (for all cells in C-337 and cells C-333-2.2, C-333-5.1, C-333-5.3, C-333-6.5, and C-333-6.7), or 118 psig (all other cells in C-333) is maintained. The minimum operating pressure is slightly above the low pressure lockout device setting (if the lockout actuates, the breaker is inoperable until air pressure is restored to a higher value).
3.9.1.3.3 14-kV Feeder Cables The feeder cables deliver power from the 14-kV switchgear to the process and auxiliary substations.
The 14-kV feeder cable system includes all cables delivering power from the 14-kV switchgear, and the structures necessary to support them. The cables are installed in either underground conduit or overhead cable trays which support, protect, and route each feeder from the 14-kV switchgear ACB to the process or auxiliary substation. The type of support system used for each cable is dependent upon a number of factors, including specific installation requirements and the required route. Each cable is electrically inetM and shielded to provide a reliable barrier between conductor voltage and the surroundmg earth potential.
The 14-kV overhead cables are positioned to avoid mechanical damage by vehicular traffic.
3.9.1.3.4 Synchronous Condensers Since the PGDP load is mostly induction motors, a lagging power factor is produced which must be corrected to provide acceptable area voltages. Both synchronous condensers and static capacitors are used for power factor improvement to maintain voltage levels.
There are eight synchronous condensers; four in the C-531 switch house, two in the C-537 switch house, and two in the C-535 switch house. The synchronous condensers are actually large, hydrogen-cooled, three-phase synchronous motors running overexcited. They are typically rated at 50,000 kVAR at 14-kV. Their output is determmed by the amount of field excitation applied and terminal voltage.
Each synchronous condenser is tied to a 14-kV bus via cables and an ACB. Protective relaying devices are located in the switch house control room.
In addition to protective relays, safe operation is dependent upon proper lubrication and cooling.
Instrumentation monitors temperatures of bearings and cooling gases, oil levels, and cooling gas pressures. The condenser shell contams hydrogen for the cooling gas, consequently strict procedures for purging with carbon dioxide and air are followed before entry by personnel. Automatic sprinkler systems are provided underneath the units and around the lube oil pumps. Actuation of these sprinklers also shuts down and valves off associated lube oil pumps. Low oil level alarm and subsequent shutdown are provided.

2.4.4 GENERAL LBIITING CONDITIONS FOR OPERATION 2.4.4.12 CASCADE CELL TRIP FUNCTION (continued)
W BASIS:
4.
The accident analysis presented in SAR chapter 4 discusses numerous cascade cell-related scenarios (e.g., 4.3.2.1.2, 4.3.2.1.5, 4.3.2.1.6, 4.3.2.2.2, 4.3.2.3.2., and 4.3.2.4.1) in which operating personnel respond to certain process conditions and alarms by de-energizing the process motors (" tripping the cell"), thus bringing the cell below atmospheric pressure. In order to initiate a cell shutdown, the DC control and trip power circuit must be functional. In order to demonstrate the reliability of the cell trip function, planned cell shutdowns will be initiated from the ACR for "00" and "000" cells, and at the local cell panel for C-310 cells, with any manual cell trip failures (regardless of initiator) being documented. The same mechanisms apply to C-310 cells with the exception of the ACR cell trip button which is not provided for C-310 cells.
The minimum air pressure required to trip the "000" breakers varies with the breaker type. The minimum required breaker actuation pressure for the "000" breaker groups and the bases for those values are identified in SAR Section 3.9.1.3.2. The minimum DC control voltage is 210 l
volts DC. Control components required for cell trip are rated to operate at 200 VDC or greater; l
however, the muumum voltage rating for the battery banks is 210 VDC and thus is the limiting l
equipment requirement.
l The alternate means of cell shutdown referred to in required action A.1 are discussed in SAR Table 4.3-2 for the "00" cells and includes an alternate means of shutdown from the ACR. For the "000" cells, alternate shutdown is manually accomplished from the switch house if DC power is unavailable; or, from either the switch house, relay house, or C-300, depending on the status of individual breaker air tank pressure.
