GE Feeder Management Relay 750 Instruction Manual page 290

8.3 METERING
1. Repeat Steps 2 to 5 above.
2. Record the measured current demand at 1, 2, 3, 4, 5 and 6 minutes after the application of current. The demand, in
percent of injected current, should be as follows:
TIME (MIN.)
Demand (% of Input)
For Rolling Demand (for example, a time interval setting of 5 minutes), the procedure is as follows:
1. Repeat Steps 2 to 5 above from Thermal Exponential Demand above.
2. Record the measured current demand at 1, 2, 3, 4, 5 and 6 minutes after the application of current. The demand, in
percent of injected current, should be as follows:
TIME (MIN.)
Demand (% of Input)
b) REAL POWER DEMAND
For these tests, refer to the figures on page 8–3 for test connections. The expected accuracy is as follows:
Expected Accuracy: ±2.0% of full scale

Follow the procedure in Current Demand on page 8–13, except that the injected and monitored parameter is watts.
c) REACTIVE POWER DEMAND
For these tests, refer to the figures on page 8–3 for test connections. The expected accuracy is as follows:

Follow the procedure in Current Demand on page 8–13, except that the injected and monitored parameter is vars.
d) APPARENT POWER DEMAND
For these tests, refer to the figures on page 8–3 for test connections. The expected accuracy is as follows:
