International Way, D-107 Portland, Oregon 97222 ALASKA POWER AUTHORITY Metering Audit Summary Utility Systems and Applications, Inc. provided testing, calibration and verification for metering points at Alaska Power Authority facilities in Wrangell, Petersburg, Ketchikan, Tyee and Swan Lake, Solomon Gulch, Meals Substation, Pump Stations 1l and 12, Kodiak and Terror Lake, Alaska. The following report, along with the audit sheets for each metering point, detail our findings, observations and recommendations. I. METER AUDIT CRITERIA AND PROCEDURE Each metering point was tested and evaluated in a standard manner, which included some or all of the following procedures and techniques. A. Meter _Test.and Calibration 1. Each KWH meter was isolated from its circuit and "as found" tested for Full Load, Light Load, Power Factor and Balance, In addition, those meters equipped with demand registers were checked for Demand Zero Point, Demand Rise Rate and Demand Reset Time. 26 Each meter was adjusted and necessary to operate within the following tolerances where possible. a. Full Load and Light Load: at least plus or minus 0.3% accuracy b. Power Factor: at least plus or minus 0.75% Cre Balance: no more than 0.5% variation among elements Due to defects, some meters could not be adjusted to meet the above tolérances; this is discussed in Section II A of this report. B. Magnetic. Tape Recorder, Packages The KWH and QH meters associated with these packages were tested as noted in Section A above. In addition, the pulse initiators were checked for proper operation and the pulse per revolution rate was checked against nameplate rate. The pulse values were also calculated and marked in the appropriate place on the recorder face plate. Magnetic. Tape Recorder. Metering. Packages Most packages do not have provision for testing (test switch) and on one, the test switch is incorrectly wired and cannot be used in testing. In these packages, it is not possible to seal the individual meters because they do not have individual glass covers. If you were to seal the package cover, the Magnetic tapes would be inaccessible for monthly changes. Norms! proce 1s 7 reseal methly, C.~'t de ie Jes Oose os AVA Cinrot ge fo ses mdhy/, : Pulse values on all the magnetic tape recorder packages are 100 KWH or Q-Hour per pulse. Some meters have to turn 15 disk revolutions for one pulse. These are very low pulse rates which give a demand definition of 400 KW. Pulse rates could be ten times as fast and still not be close to tape saturation. This would greatly improve demand definition. Ops preblex Because the meters in these packages do not have separate covers, dirt is a problem. There is no way to prevent heavy contamination. An additional digital recording package should be considered at Bailey Substation. Gaek L. vb lan Demand_Definition.of.mechanical..Demand.Register special register ratios have been ordered to give multipliers of 1,000 on many of the meters. As a result, many of these have poor demand definition and cannot be read closer than 500 KW. Const [ena bl erm III. oe @ RECOMMENDATIONS The following is a review of the recommendations listed on the Audit Test Sheets. A. Wrangellsubstation 1. Verify accuracy class of all current transformers, If magnetic tape package C.T.s are not 0.3 accuracy class, they should be replaced. Fae One of the switchboard meters should be returned to the factory for rebuilding. ops Install test switch for remote magnetic tape recorder package. Increase pulse initiator output by at least a factor of 10. B. Wrangell_Switchyard 1. 2. 3 The C.T. ratio should be verified. The metering is three wire and should be replaced with four wire metering. Register demand definition is poor and a magnetic tape could be installed to improve this. c. Petersburg.Substatian 1. 2. Two meters have incorrect demand register scale plates. One switchboard meter has the incorrect cover, which makes it impossible to reset the demand without removing the cover. This allows dirt to contaminate the meter. The metering is three wire, but should be four wire. The metering on the magnetic tape package should be changed to four wire as it appears this is the billing meter. (This will require installation of three P.T.s). Consideration should be given to installing four wire metering on the other two circuits also. The customer will have line to ground loads in the future. None of the current transformers are 0.3 accuracy class and should at least be replaced on the magnetic tape package metering. By The "Out" meter is wired for "In" power. 6. A test switch should be installed to enable convenient testing for the magnetic tape package. Ure The pulse rate should be increased at least a factor of 10 on the magnetic tape package in order to improve demand definition. 8. Remote the recorder from the metering package. Tyes Tie C.T. ratio and accuracy class needs to be verified as C.T.s were inaccessible on the station service metering. 2. The generator C.T.s are not 0.3 accuracy class and are relay class. 5 The station total metering is three wire but the system is four wire. This metering should be changed to four wire for best accuracy. 4. The test switch should be rewired to enable easier testing for the magnetic tape metering package. Se The pulse rate to the magnetic tape should be increased by at least a factor of 10 to improve demand definition. 6. Remote the recorder from the metering package. Swan.Lake 1. The potential transformer should be disconnected from the metering circuit for both station service meters. They are not necessary and create inaccuracies inthe registration. 2. Install test switches or "slide" kits to enable easier testing of station service meters. Sie Station service C.T.s are not 0.3 accuracy class. 4. Due to loading of P.T.s and wire length, a separate potential cable should be run to the generator meters. oe @ Soelomen.Gulch 1. Replace the Fuji meters with magnetic suspension type. 2. Verify C.T. ratio and accuracy class. 3% Change metering to four wire WYE. 4. Change instrument transformers to revenue class. Meals.Substation Le Correct the wiring on the 25 KV busp meter. 2 Verify C.T. and P.T. ratio and quality. Pump..Station #11 1.

CONCLUSION Many of the installations are in considerable error and, due to the large amounts of power they meter, should be repaired. Those installations where billing occurs should definitely be brought into plus or minus 0.3 accuracy. The meters themselves, with a coupled of exceptions, were left better than plus or minus 0.3% accuracy. If demand is to be billed in the future, magnetic tape recorder packages or similar devices should be installed to provide suitable demand definition. lity Systems & Applications, Inc. us, Uti SBA January 23, 1986 Mr. Harry L.

METER AUDIT CRITERIA AND PROCEDURE ALASKA POWER AUTHORITY Metering Audit Summary Utility Systems and Applications, Inc. provided testing, calibration and verification for metering points at Alaska Power Authority facilities in Wrangell, Petersburg, Ketchikan, Tyee and Swan Lake, Solomon Gulch, Meals Substation, Pump Stations 11 and 12, Kodiak and Terror Lake, Alaska. The following report, along with the audit sheets for each metering point, detail our findings, observations and recommendations. I. METER AUDIT CRITERIA AND PROCEDURE Each metering point was tested and evaluated in a standard manner, which included some or all of the following procedures and techniques. A. Meter Test.and Calibration iL Each KWH meter was isolated from its circuit and "as found" tested for Full Load, Light Load, Power Factor and Balance. In addition, those meters equipped with demand registers were checked for Demand Zero Point, Demand Rise Rate and Demand Reset Time. 2. Each meter was adjusted and necessary to operate within the following tolerances where possible. a. Full Load and Light Load: at least plus or minus 0.3% accuracy b. Power Factor: at least plus or minus 0.75% Cc. Balance: no more than 0.5% variation among elements Due to defects, some meters could not be adjusted to meet the above tolerances; this is discussed in Section II A of this report. B. Magnetic. Tape Recorder, Packages The KWH and QH meters associated with these packages were tested as noted in Section A above. In addition, the pulse initiators were checked for proper operation and the pulse per revolution rate was checked against nameplate rate. The pulse values were also calculated and marked in the appropriate place on the recorder face plate. Identification Where necessary, the meters were given additional identification markings and the dial multiplier was calculated and marked on the multiplier tag. Current Transformer and Potential Transformer Ratio and Quality Veification. Where possible, each C.T. and P.T. was visually inspected and nameplate data checked for ratio and quality. Current_Transformer..Burden. Checked The burden test is basically a proof test to determine how well the C.T. can provide constant current with increasing loads. "Good" C.T.s are those in which little current drop occurs when high resistance (up to 6 ohms) is inserted into a C.T. secondary circuit. "Bad" C.T.s show a sharp drop at low currents with small additions of load. This test also indicates whether there are any "shorts" in the C.T. secondary circuit. Phase Angle. Analysis Where there was sufficient loading, phase angle readings were taken to verify correctness of wiring and power load factor. In addition, the meter disk was timed and KW demand calculated and compared to actual load current and phase angle. Meter.Seals Each meter, except those in the magnetic tape packages, was sealed with a pressed lead seal. The seal mark number pressed into these lead seals is "87". IL GENERAL COMMENTS II. GENERAL COMMENTS A. Meter Tests The Fuji Meters at Solomon Gulch are of obsolete design and were considerably out of calibration. On one of them, we could not adjust the Light Load. Some meters do not have enough adjustment left to fully bring them into 0.3 accuracy. Several other meters have little or no adjustment left. Due to this problem, many of these meters should be returned to the factory for rebuilding. (See Audit Summary dated June 8, 1984.) Current..Transformer.Quality Several installations did not have 0.3 metering accuracy class current transformers for the KWH metering. The C.T.s that are in service are relay class and may not be close to ratio at metering currents. Unnecessary..Potential.Transformers The two station service meters at Swan Lake were connected to the secondary of the P.T.s (277 to 120), but these are 277 volt meters. Improper.Metering Several installations were metered three phase three- wire, but should be three phase four-wire. These occur at Wrangell Switchyard, Petersburg, Tyee, Solomon Gulch, Terror Lake, Kodiak Airport Substation, and Swampy Acres. SIn".and"Qut" Metering Some installations have "In" and "Out" metering, but the "Out" meter is wired the same as the "In" meter. They are at Petersburg and Tyee. There is no "Out" metering at Bailey Substation, so when Ketchikan feeds power to Swan Lake, this power cannot be registered. Magnetic Tape Recorder. Metering. Packages Most packages do not have provision for testing (test switch) and on one, the test switch is incorrectly wired and cannot be used in testing. In these packages, it is not possible to seal the individual meters because they do not have individual glass covers. If you were to seal the package cover, the Magnetic tapes would be inaccessible for monthly changes. Pulse values on all the magnetic tape recorder packages are 100 KWH or Q-Hour per pulse. Some meters have to turn 15 disk revolutions for one pulse. These are very low pulse rates which give a demand definition of 400 KW. Pulse rates could be ten times as fast and still not be close to tape saturation. This would greatly improve demand definition.

It is a B wire meter on a 4 Wire WYE system. The MP = 125/36 giving a 100 Kwh/Pulse on channel B and 100 QH/Pulse on channel C. The metering package must be opened each month to change the mag tape. This brings in a large amount of dirt to contaminate these meters. The test switch is improperly wired to use for testing. ***RECOMMENDATIONS*** Change to 4 Wire metering. Install a pulse initiator with an MP of 25/72 to bring demand definition to 40 KW. Remote the recorder so as to not contaminate the meters. Rewire the test switch.

This makes it difficult and time consuming to test the meters. The mag tape recorder is not being used. Current return circuit is not grounded. Current transformers are on OCB bushings so we couldn't verify ratio and accuracy class. Should be 0.3 accuracy. Metering potentials are taken from the CCVT which are not metering accuracy class. Error on these instruments could amount to $2,000/month. See File 1985-62 for CCVT.

They are not accessible to verify. Demand definition is poor. Each division is 500 KW. This is a 4 wire WYE system metered with a 3 wire Delta metering scheme which is inaccurate at least 5% due to the voltage unbalance amounting to $2,000/month. We couldn't verify all circuit wiring because the system was energized. If it is properly wired 3 wire Delta it could be in error as much as 5%. See file 1985-62 regarding CCVT to additional $4,900/month. CCVT are in error approximately 1.2% amounting to additional $4,900/month. ***RECOMMENDATIONS*** Verify metering current transformers as to ratio and accuracy class. Change if not 0.3 accuracy Change CCVT's to metering quality PT's (0.3 accuracy). Rebuild metering using 3 element form 9 meter.
