4-Wire Wye, 3-Element, Direct Connection Diagram
347 V L-N / 600 V L-L max.
VOLTS MODE = 4W-Wye
4-Wire Wye, 3-Element, 3 PTs Connection Diagram
Use PTs for voltages over 347 V L-N / 600 V L-L.
Wye (Star) wiring for PT primaries and secondaries.
VOLTS MODE = 4W-Wye
4-Wire Wye, 2½-Element, 2 PTs Connection
Phase B voltage (V2) displayed by meter is derived from phase A and
phase C, not measured. V2 will display a value even if no voltage is
present on Phase B. V2 values are only accurate for balanced loads.
VOLTS MODE = 3W-Wye
