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 relay Sensing Module.
Table 468 - 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

L1-N Voltage
L1-N Voltage (Parameter 57) reports the voltage in volts in reference to the T1
power terminal of the E300 relay Sensing Module.
