4-Wire Wye, 3-Element, Direct Connection Diagram
288 V L-N / 500 V L-L max.
VOLTS MODE = 4W-Wye
4-Wire Wye, 3-Element, 3 PTs Connection Diagram
Use PTs for voltages over 288 V L-N / 500 V L-L.
Wye (Star) wiring for PT primaries and secondaries.
VOLTS MODE = 4W-Wye
4-Wire Wye, 2½-Element, 2 PTs Connection
Phase 2 voltage (U2) displayed by meter is derived from phase 1 and
phase 3, not measured. U2 will display a value even if no voltage is
present on Phase 2. U2 values are only accurate for balanced loads.
