Metering
➤
Voltage values (phase, phase-to-phase, synchronism check,
neutral): 7.5 V • PTRn, 13 V • PTRn, 7.5 V • PTRS, and
7.5 V • PTRN, respectively.
➤
Power values (real, reactive, and apparent): All three currents
(I
A
n, I
B
n, I
C
n) and all three voltages (V
A
n, V
B
n, V
C

n) must be above their thresholds.
Figure 5.7 shows an example device response to the METER M command.
To reset maximum/minimum meter values, issue the METER RM command
as shown in Figure 5.8. The max/min meter values can be reset from the serial
port, Modbus, the front panel, or assertion of the RSTMXMN relay element.
The date and time of the reset are preserved and shown in the max/min meter
report.
All maximum and minimum metering values are stored to nonvolatile
memory four times per day and within one minute of the maximum and
minimum metering values being reset.
