5-2 Metering and Monitoring Date Code 20080110
SEL-387E Instruction Manual
Note: If current or voltage transformers are connected delta (DELTA_Y = D, WnCT = D) or
only one voltage is connected (TPVI = N), only total power (MW, MVAR, MVA) will
display in the METER report. This restricted calculation assumes balanced load
conditions. Setting the current voltage winding setting (VIWDG) to 12 combines the
current in Winding 1 and Winding 2 and displays their sum in the METER report.
The format for the METER report is as follows:

Demand Ammeter Function (METER D Command)
The SEL-387E Relay includes a thermal demand metering function for all three current
windings. In response to the METER D (MET D) command, the individual phase demand
currents, as well as the negative-sequence and residual demand currents for each winding, are
displayed in primary RMS amperes. If the command is typed as MET D m, where m is any
number from 1 to 32767, the report will be repeated m times in succession. In this mode
subsequent reports are not generated until the previous report has been completely sent. The
format for the METER D report is as follows:
