Space for the revenue metering should be provided in the PDC, but may be approved <br /> for outdoor installation if approved by CAISO and PG&E revenue metering <br /> representatives. <br /> Metering of plant auxiliary power during standby will be provided by a PG&E revenue <br /> metering installation on the 18kV-4.16kV transformer. This revenue meter installation will <br /> be configured to monitor auxiliary power consumption when both generator breakers are <br /> open and the plant is in a standby mode. This meter will be enabled when both generator <br /> breakers are open and disabled if either one or both of the generator breakers are closed. <br /> The final aux electric metering configuration, metering instrument transformers and test <br /> switches will must be reviewed and approved by the local utility prior to installation. <br /> Relaying class accuracy voltage and current transformers are acceptable for panel <br /> indication meter applications. <br /> Test switches will be provided for the voltage and current inputs to each meter. <br /> 4.16.2 Metering Locations <br /> Indication metering will be provided in the following locations: <br /> • Each generator(voltage, current, kW, WAR, kWHr, kVARHr, pf, and freq) <br /> • Each 18kV breaker (voltage, current, kW, and WAR) <br /> • The 4.16kV main breaker (voltage, current, kW, and WAR <br /> • Each low voltage main breaker(voltage, current, kW, and WAR <br /> • Each medium voltage motor(current)—provided motor protection relays <br /> • Low-voltage motor control centers (voltage, current, kW, and WAR <br /> • 125 VDC BOP systems: <br /> — Battery amperes (at DC switchboard) <br /> — Bus voltage (at DC switchboard) <br /> — Negative to ground(at DC switchboard) <br /> — Positive to ground(at DC switchboard) <br /> Lodi Energy Center 3.4- 10 LEC AFC <br /> 071608 Rev.A <br />
