Metering
Transformer/Line Loss Compensation
View and Set
Transformer/Line
Loss Compensation
Use the MET L and SET commands to view and set the transformer/line
losses calculated by the meter (see MET L (Transformer/Line Loss Metering)
on page 10.21). Values shown in the MET report are uncompensated.
Calculations are performed every second to compensate the average power,
demand, peak demand, and energy values, as shown in Tab le 4.11 .
