A. Suggested Validation Tests 1. Current and Voltage Check This indicator detects the loss of voltage and/or current input to the meter due to failure of the supply from one or more instrument transformers or tampering. 2. Load Profile vs. Meter Reading This checks for corruption related to the meter multiplier. 3. Intervais Found vs. Interval Expected This checks for missing intervals. 4. Time Synchronization This checks for synchronism of meter clock to Philippine Standard Time/Data Coliection System time. 5. Number of Power Outage Intervais This indicator allows periods of zero primary power to be identified. 6. Cyclic Redundancy Check /Read-Only Memory /Random Access Memory This is part of the internal components of a meter, which is automatically flagged when failing. 7. Meter Clock Overfiow Flag generated by the meter indicating failure of internal electronics. 8. Hardware Reset Flag generated by the mefer indicating failure of internal electronics. 9. Time Reset This indicates the interval in which the meter clock time has been changed creating either a shorter or longer interval. 10. Data Overfiow on Interval! Page 1 of 4 al & MS B&B === dc2021-06-0012-pages-45.ppm === C C ANNEX A DOE DEPARTMENT CIRCULAR NO._ This indicates that the meter is creating more pulses than it can record in an interval or Data Collection System (DCS) can accommodate in an interval. 114.Number of Channels The actual number of data channels from the meter does not maich the number expected at the data collection System. 12. Changed Device ID The internal device identifier does not match the value registered at the data collection system. 13. Watchdog Time Out This is the failure of the meter to return data in response to a poll within the required time frame. This is reported by some recorders when a watchdog register is tripped or activated. 14, Parity Error This indicator is determined by a parity error bit that is set by a recorder on a channel of data during status check or read/write function. 15. Event Log Check This checks error messages and alarms recorded by the meter. Suggested Daily Estimation Procedures Any value in the metering data that falis outside the maximum and minimum range of the metering data as recorded in the database of the Refail Metering Services Provider may be estimated using the following: 1. Historical Values The values with ‘uncertain’ status may be replaced using the following historical data: a. Value during the same hour last week, b. Value during the same hour the previous day, and c. Average of the values during the whole previous day. 2. Backup Meter The values with ‘uncertain’ status may be replaced with the values from the backup meter during the same hour. 3. Previous Hour Data Page 2 of 4 + ¢ a @ === dc2021-06-0012-pages-46.ppm === ANNEX A DOE DEPARTMENT CIRCULAR NO._ The values with ‘uncertain’ status may be replaced using the reading from the previous hour. C. Suggested Monthly Estimation Procedures 1. Interpolation of Metering Data if metering data of one (1) to four (4) consecutive fifteen-minute intervals are missing, metering data may be estimated by means of interpolation between the available intervals. Back-up Meter Data If metering data of more than four (4) consecutive fifteen-minute intervals are missing, metering data from the back-up meter may be directly substituted for the missing data from the main meter provided that the historical difference of metering data between the main and backup meters does not exceed more than 0.2%. if the historical deviation exceeds 0.2% but not more than 0.6%, a correction factor based on the historical difference between the main and backup meters is suggested to be applied on the metering data from the backup meter before it is substituted for the missing data. From Grid Off-Take Meter lf both the main and backup meters fail, the metering data on the metering point of the facility of the Contestable Customer may be estimated using the metering data from its grid off-take meter. The metering data of the Contestable Customer may be estimated by adjusting the metering data of its grid off-take meter using a historical factor obtained through the comparison of the historical grid off-take metering data and historical Contestable Customer main metering data. This method of estimation is not applicable for variable loads whose historical load profile is indeterminate. Scientific Method of Estimation If there is a loss of one of the phase voltages and currents, estimation may be performed through the scientific method of calculation using the average remaining phase voltages or currents of good data from the historical load profile. Historical Meter Data If the above methods do not provide reasonable values, the following: historical data from the main meter may be used for estimating missing values: a. Values during the same hour of the previous day with the same day type (i.e., weekday or weekend), b. Values during the same hour of the same day last week recorded by the same meter (i.e. Saturday, Sunday, Holidays), and Page 3 of 4 SS $ «8 @ === dc2021-06-0012-pages-47.ppm === ANNEX A DOE DEPARTMENT CIRCULAR NO._ c. Average value of the values during the same hour of the same day of the three (3) previous weeks recorded by the same meter. This method of estimation is not applicable for variable load whose historical load profile is indeterminate. Page 4 of 4 - L © @&
