The results of this analysis can also apply to any ABB Model ITE-27H Undervoltage Relay used at RBS, but care must be taken when applying these results. Specifically, in order to apply the results of this analysis to other similar devices, the devices must meet the criteria listed in Section 3.5.3 of Reference 4.1.3, "Considerations When Combining Instruments Into a Single Group".6Method of Analysis 6.1The methodology used for this analysis is Reference 4.1.3, which is written in accordance with Reference 4.1.4, using References 4.1.1,4.1.2 and 4.1.7 to supplement. An overview of the methodology is given herein, and any deviation from Reference4.1.3 or any supplemental methods used herein are described. 6.2This analysis determines the drift values for the subject instrumentation by analysis of historical As Found / As Left data from calibration records. Drift for a given device for a calibration period is determined by subtracting the previous As Left setting from a more recent As Found setting. The time interval for that calibration period is determined by subtracting the previous date from the more recent date, in units of days. All retrievable As Left and As Found data is collected for each calibration performed on each device covered by this report, for the study period. From this information, the drift and calibration interval is generated for each possible instance. Per Section 3.4.2 of Reference4.1.3, "The goal is to collect enough data for the instrument or group to make a statistically valid pool." The devices covered by this report are currently calibrated on an 18 Month basis, and the proposed extension is for a 24 Month nominal calibration interval. Therefore, a study period of 10 years represents more than six of the present calibration cycles, and five of the proposed calibration cycles, which is adequate to understand the component's performance over time. Also, a sufficient number of valid drift values are provided as a result of the selected study period to make a statistically valid pool. Therefore, As Found and As Left Data values are entered from calibrations occurring for approximately the last 10 years. 6.3Determination of the Analyzed Drift is generally accomplished through the following steps.6.3.1Gather and Generate Raw Drift Data: In addition to gathering the As Found and As Left data, and computing the drift values and time intervals, this step also involves an investigation into whether all of the devices should be analyzed together, or whether they should be separated into smaller analysis groups. Additionally, this step involves careful screening of the input data for errors or other situations that would not allow proper determination of drift

.6.3.2Determination of Outliers and Statistical Summary: In order to properly model the drift characteristics for a device, it could be proper to remove up to one more data value, which obviously does not conform to the vast majority of the data. A t-Test is DRIFT ANALYSIS G13.18.6.3-006ENGINEERING DEPARTMENT Revision 0 RIVER BEND STATION PAGE 10 OF 14 performed on the data to detect any outliers, and remove up to one if appropriate, per the guidelines of Reference 4.1.3. Additionally, the basic statistical values which describe the group of drift data are derived in this step, including such parameters as Mean, Standard Deviation, Count, Median, Minimum, Maximum, etc.6.3.3Tests for Normality: Per Reference 4.1.3, a statistical test (W or D-Prime, depending on sample size) is performed on the drift data to support the hypothesis that the data conforms to a normal distribution. If this test is unable to support that hypothesis, then a Coverage Analysis is performed to ensure that the data can be conservatively modeled by a normal distribution and to provide an adjustment to the standard deviation of the drift model, if necessary to conservatively envelop the observed data population. 6.3.4Time-Dependency: Per Reference 4.1.3, Scatter Plots and a time-based Binning Analysis are developed for the data to establish the time-dependency of the drift. If enough drift data exists for significantly different time intervals, regression analysis is performed to aid in the determination of time-dependency. The drift data is determined to be strongly time dependent or moderately time dependent, for the purpose of extrapolation. 6.3.5Analyzed Drift Derivation and Characterization: The drift values are determined for the current calibration interval. These values are conservatively extrapolated to the desired calibration interval, based on the methods prescribed in Reference 4.1.3,depending on the degree of time-dependency derived for the drift data. 6.4The mathematical computations of the statistical analysis are performed within an Excel spreadsheet. Supporting information from the spreadsheet is printed out in the form of Attachment 1 to this analysis. Microsoft Excel spreadsheets generally compute values to an approximate 15 decimal resolution, which is well beyond any required rounding for engineering analyses. However, for printing and display purposes, most values are displayed to lesser resolution. It is possible that hand computations will produce slightly different results, because of using rounded numbers in initial and intermediate steps, but the Excel computed values are considered highly accurate in comparison. 6.5Acceptance Criteria: Since the purpose of the analysis is to generate a value and description of the characteristics of the drift of the evaluated make/model, there are no specific acceptance criteria. 7Analysis 7.1Gather and Generate Raw Error Data 7.1.1Specifically, this analysis addresses ABB Model ITE-27H Undervoltage Relays, with the tag numbers as shown in Table 1.2-1 of this analysis. These relays have identical manufacturer and model numbers, identical settings, and are used in identical applications. Therefore, all data is properly pooled for analysis, and no specific pooling tests are required. 7.1.2A screening of the initial input data from pages 1 through 3 of Attachment 1 was performed. To help identify erroneous data, an informal critical T-test was performed, with the Critical T values reduced incrementally until approximately 10% of the data population was identified as outliers. Those outliers were researched, DRIFT ANALYSIS G13.18.6.3-006ENGINEERING DEPARTMENT Revision 0 RIVER BEND STATION PAGE 11 OF 14 and no data errors were revealed as shown in Table 7.1.4-1. The specific informal T-tests performed are not documented, as they are only used as tools to identify potentially erroneous data and do not contribute to the analysis of the valid data. 7.1.3Pages 1 through 3 of Attachment 1 provide a listing of the initial As Found and As Left data from available historical plant calibration records for the subject UV Relays. Note that the calibration dates are also recorded, and notes are provided to clarify the activities performed or to provide additional information about the data, as appropriate. This data was entered into an Excel spreadsheet for computation of the drift values, time intervals between calibrations and statistical analysis. 7.1.4Data not entered into the analysis is listed in the table below, showing the reasoning used in not entering the data. Table 7.1.4-1 Data Not Entered in the Drift Analysis ProcedureNumberTag Number SurveillanceDate(s)Comments/DispositionNoneNoneNoneNone7.1.5Per the methodology of Section 4.1.1.11 of Reference 4.1.3, drift is computed by subtracting the As Left data of one calibration from the As Found data of the next calibration, as documented in pages 4 through 6 of Attachment 1. These pages also document the time interval between calibrations (in the number of days and months) by subtracting the As Left date of one calibration from the As Found date of the next calibration, per Section 4.1.1.10 of Reference 4.1.3. Pages 4 through 6 of Attachment 1 import the Sequence ID, the Tag No., the AF / AL flags, the dates of calibration and the As Found and As Left data from pages 1 through 3 of Attachment 1 and computes the interval between calibrations. Pages 4 and 5 of Attachment 1 compute the drift values and summarize the time intervals computed.As an example of the equations used, the first drift value and time interval are computed as follows. The rest of the values are computed identically. Drift (Seq 1)= AF (2/17/08) - AL (5/08/06) [For Tag ENS-SWG1A-27-1A] = 48.90 (From Seq. 1 on Left) - 49.09 (From Seq. 4 on Left) = -0.19 VAC Cal Interval (Seq 1) = 2/17/08 - 5/08/06 = 650 Days Cal Interval (Mo.) = Cal Interval (Days) x 12 Months / 365.25 Days = 21.4 Months DRIFT ANALYSIS G13.18.6.3-006ENGINEERING DEPARTMENT Revision 0 RIVER BEND STATION PAGE 12 OF 14 7.2Determination of Outliers and Statistical Summary 7.2.1The outlier analysis is recorded on pages 7 and 8 of Attachment 1 to this drift analysis. This page displays the Sequence No., Tag No., Drift, and Calibration Interval (in units of Days). The critical T value used in the outlier analysis comes directly from Table 2 of Reference 4.1.3. As shown on page 7 of Attachment 1, one outlier was detected and removed. The Final Data Set (FDS) for this analysis is documented on pages 7 through 8 of Attachment 1 and, except for the one removed outlier, is identical to the original data set. 7.2.2A summary of the required statistical values for the Final Data Set, per Section 4.2 of Reference 4.1.3, is developed on page 7 of Attachment 1. Cell formulas for the determinations of statistical quantities are used directly from Section 4.2 of Reference4.1.3.7.3Tests for Normality 7.3.1Since the FDS contains less than 50 samples, the W Test is performed on the data to test for normality, as shown on page 9 of Attachment 1. Per the methodology of Section 3.7.2 of Reference 4.1.3, the details of the W Test methodology are shown in Reference 4.1.7. Equations used are listed on page 9 of Attachment 1. Since the calculated W statistic (0.9569) is greater than the critical value for W (0.9410), this test does not reject the assumption of normality for this data set. Therefore, the data is established as normally distributed, and no coverage analysis is necessary. 7.3.2Since the W Test did not reject the assumption of normality, a Coverage Analysis is not necessary, but a Histogram is developed for information only. The Histogram is developed and documented on pages 10 and 11 of Attachment 1, per Sections 3.7.5 and 4.4 of Reference 4.1.3. To generate the Histogram data, the drift values are categorized into 12 bins, in relation to the mean and standard deviation. These bins are generated in multiples of 1/2 Standard Deviation increments, and the bin maximum values are derived in accordance with the methods given in Section 19 of Reference4.1.4. (See page 10 of Attachment 1 for specific formulas used for the maximums.)

The expected populations within each bin are developed from normal distribution percentages, as shown on page 10 of Attachment 1.7.4Time-Dependency7.4.1In order to determine time-dependency of the drift data, the data is first plotted as a scatter plot on page 12 of Attachment 1, in accordance with the methodology of Section 4.5.1 of Reference 4.1.3. The trend line within this scatter plot starts at a small negative value and crosses zero towards the end of the analysis period. The data scatter appears to increase slightly over time. The trend line and the associated equation are noted on the scatter plot on page 12 of Attachment 1. 7.4.2The binning analysis is performed on page 13 of Attachment 1. The drift and time interval data are divided into bins, based on the intervals between calibrations as defined in Section 3.8.3.1 of Reference 4.1.3. Statistical summaries for each bin, including count, mean, standard deviation, mean time interval and maximum observed time interval are computed. Excel functions are used to determine the statistical summary values for each bin, and are used explicitly from Sections 4.2.1, DRIFT ANALYSIS G13.18.6.3-006ENGINEERING DEPARTMENT Revision 0 RIVER BEND STATION PAGE 13 OF 14 4.2.2, 4.2.3 and 4.2.7 of Reference 4.1.3. This information is presented on page 13 of Attachment 1. Per Section 3.8.3.4 of Reference 4.1.3, after removing those bins with 5 or less data points and those with less than or equal to 10% of total population, only Bins 4 and 5 remain.

Page 14 of Attachment 1 displays a plot of the mean and standard deviations of the drift data versus the average time interval between calibrations for the subject bins, in accordance with Section 4.5.2 of Reference 4.1.3. It also provides all of the binning parameters and statistics that are a part of the binning analysis. The mean value of the data starts from a negative value in Bin 4, crosses zero and goes positive for Bin 5. Also, from this plot, the standard deviation increases from Bin 4 to Bin 5. In addition, the ratio of the variances (Bin 5 / Bin 4) is compared to the F critical value, as directed by Section 4.5.2 of Reference 4.1.3. Only the standard deviation plot could be indicative of potential time dependency, but strong time dependency is not indicated from the variance test (Sections 3.8.3.4 and 4.5.2 of Reference4.1.3).7.4.3Per Section 3.8.4 of Reference 4.1.3, a drift regression analysis is performed within pages 15 and 16 of Attachment 1 (labeled "Regression-Drift"). The equations and functions used by Excel are taken specifically from Section 3.8.4 of Reference 4.1.3.The regression analysis output shows an R Squared Value (0.042874) less than 0.09, a P Value greater than 0.05 (0.193957) and F Value (1.746985) less than F Critical (3.238096). These results all indicate a bias portion of drift that is not time-dependent. Also, the regression line crosses zero within the analysis period, which per the last paragraph of Section 3.8.4 of Reference 4.1.3, is not expected and is an improper model of the drift-versus-time characteristic of the device. The fact that this is an improper model of the drift-versus-time characteristic of the device confirms the time-independent conclusion of the three statistical tests. The bias portion of drift is conservatively treated as moderately time-dependent for the purpose of extrapolation. 7.4.4Per Section 3.8.4 of Reference 4.1.3, an absolute value drift regression analysis is performed within pages 17 and 18 of Attachment 1 (labeled "Regression - AV of Drift"). The drift data is converted into absolute value via the Excel ABS function for each drift data value. The equations and functions used by Excel for the Regression analysis are taken specifically from Section 3.8.4 of Reference 4.1.3.This regression analysis output shows an R Squared Value (0.023738) less than 0.09, a P Value (0.336156) greater than 0.05, and an F Value (0.948294) less than F Critical (3.238096). These results all indicate a random portion of drift that is not significantly time-dependent. The absolute value drift regression line increases over time, and the binning plot shows an increasing standard deviation over time. Based on these results, per Section 3.8.4 of Reference 4.1.3, the random portion of drift is conservatively treated as moderately time-dependent for the purpose of extrapolation.7.5Analyzed Drift (DA) Derivation and Characterization 7.5.1As shown on page 19 of Attachment 1, per Section 3.11 of Reference 4.1.3, the drift bias error is evaluated for significance. The critical value for significance of the bias term is computed and shown therein. The bias is determined to be negligible.Therefore, the computed Analyzed Drift Bias term (DAbias) is negligible.

DRIFT ANALYSIS G13.18.6.3-006ENGINEERING DEPARTMENT Revision 0 RIVER BEND STATION PAGE 14 OF 14 7.5.2Per Section 4.6.6 of Reference 4.1.3, the random portion of the Analyzed Drift is determined from multiplying the standard deviation of Bin 5 by the Tolerance Interval Factor (TIF), and extrapolating as required to a calibration interval of 30 months. The random portion of drift has been determined to be moderately time-dependent for the purpose of extrapolation. For conservatism, the standard deviation of Bin 5 is used with the average observed time interval from Bin 5 on page 13 of Attachment 1 as the starting point. The TIF is obtained from Table 1 of Reference4.1.3 as 2.445 for a 95/95 significance. The computation of this value is shown on page 19 of Attachment 1 to result in a DArandom(extrap) term of ! 0.392 VAC for a 30 month (24 months + 25%) calibration interval. 8AttachmentsAttachment 1 - Analysis Spreadsheet (19 pages)

2.Obtain mean, standard deviation, and sample size.

3.Establishing bins in 1/2 sigma increments from the mean to 2.5 sigma in both directions, derive the upper bin limits, inunits of drift, based on the values of the mean and standard deviation. 4.Obtain expected frequency for a normal distribution in each bin.5.Manually compute the number of observed drift data points within each bin, and list under observed frequency.6.Plot the Expected Frequency and the Observed Frequency Data on the Histogram for comparison to each other.Results:Since the data passed the W Test for normality, a Coverage Analysis is not necessary. The Histogram shows that the data conforms closely to a normal distribution.

The reviewer independently generated the G13.18.6.3-006 results. In the table below the results of the validation for the G13.18.6.3-006 values and the values produced by Lotus 1-2-3 and Quattro Pro are illustrated for the Final Data Set - after removal of the single outlier. The results from Lotus 1-2-3 and Quattro Pro validated the calculation G13.18.6.3-006 results generated by MS Excel. Minor differences in the values between the MS Excel generated results and the Lotus 1-2-3 and Quattro Pro generated results were reviewed and can be attributed to rounding and conversion between applications.
