Three-phase four-wire circuit
Using PT (potential transformer)
When the voltage of the device to be measured exceeds the maximum voltage range of this
product, a PT (potential transformer) may be connected. The connection circuit is shown for
single-phase, two-wire circuits. For other circuits, similarly connect a PT for each phase.
When a PT is used, it is necessary to set the scaling that corresponds to the transformer
ratio.
