CURRENT
• A, B, C CURRENT : Displays the current in each phase corresponding to the A, B, and C
phase inputs. Current will be measured correctly only if the
CT PRIMARY
is entered to
match the installed CT primary and the CT secondary is wired to match the 1 or 5 A
input. If the displayed current does not match the actual current, check this setpoint
and wiring.
• Iavg/Vavg : Displays the average of the three phase currents and three voltages. This
line is not visible if the
VT WIRING
setpoint is set to “Single Phase Direct”. L-N is displayed
when
VT WIRING
is set to “4 Wire Wye /3 VTs”, “4 Wire Wye Direct”, “4 Wire Wye / 2 VTs”,
or “3 Wire Direct”. L-L is displayed when
VT WIRING
is set to “3 Wire Delta / 2 VTs”.
