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 Electronic Overload Relay Sensing Module.
Table 257 - L2-L3 Voltage (Parameter 54)
Table 258 - L3-L1 Voltage
L3-L1 Voltage (Parameter 55) reports the voltage in volts in reference to the T3
and T1 power terminals of the E300 Electronic Overload Relay Sensing Module.
Table 259 - L3-L1 Voltage (Parameter 55)
Average L-L Voltage
Average L-L Voltage (Parameter 56) reports the average voltage of the monitored
L-L voltages. When Single or Three Phase (Parameter 176) is set to
Three Phase,
Average L-L Voltage is calculated as follows:
Average L-L Voltage = (L1-L2 Voltage + L2-L3 Voltage + L3-L1 Voltage) / 3
When Single or Three Phase (Parameter 176) is set to Single Phase, Average L-L
Voltage is calculated as follows:
Average L-L Voltage = (L1-L2 Voltage + L2-L3 Voltage) / 2
