Following is the display of voltages when a 2Vpn+Vr connection mode is chosen
(two phases - neutral plus earth voltage). The visualisation depends on connection
mode.
UA
57.00 V
Displays the RMS voltage value of phase A.
UB
57.00V
Displays the RMS voltage value of phase B.
UN
3.00V
Displays the earth voltage value.
Max UA Rms
127.23 V
Displays the true RMS maximum voltage value for
phase A.
Max UB Rms
136.28 V
Displays the true RMS maximum voltage value for
phase B.
Average UA Rms
98.25 V
Displays the true RMS average voltage value for
phase A.
Average UB Rms
97.88 V
Displays the true RMS average voltage value for
phase B.
