Voltage Monitor
The E300 relay’s voltage monitor diagnostics provides information on the voltage
being supplied to the load. The voltage diagnostics include three-phase voltage,
phase imbalance, phase rotation, and frequency.
L1-L2 Voltage
L1-L2 Voltage (Parameter 53) reports the voltage in volts in reference to the T1
and T2 power terminals of the E300 relay Sensing Module.
Table 466 - L1-L2 Voltage (Parameter 53)
L2-L3 Voltage
L2-L3 Voltage (Parameter 54) reports the voltage in volts in reference to the T2
and T3 power terminals of the E300 relay Sensing Module.
