3-Wire Grounded Wye, 3-Element Direct
The configuration requires that the transformer secondary star-point is
grounded. The phase-to-ground voltages must be within the meter's range.
Volts Mode = 4W-Wye
Single Phase Connection Diagram
Connect the two voltage phases (180° apart) to the V1 and V2 inputs, and
the CT outputs to the I1 and I2 input pairs. Unused meter inputs are
grounded.
Volts Mode = 2W
For optimum meter performance, ensure phase rotation sequence is
respected.
