Installing Potential Transformers for Three-Phase Service Greater Than 277V

Potential transformers are required when metering services greater than the rated voltage input of the meter. Potential transformers are used to reduce the line-to-neutral voltage of the service to 120V. The accuracy class should be 0.3% or better, with a burden rating of 30VA.

For applications in Canada, Measurement Canada approved potential transformers are required. Measurement Canada requires an accuracy class of 0.3% or better, with a 150VA rating.

NOTE: Potential transformer burden depends on the control voltage source. If control voltage is provided separately (not derived from the metered voltage), then lower transformer burden may be acceptable. Contact your local Schneider Electric representative for details.

Mount the potential transformer enclosure between the supply voltage and the PowerLogic meters as shown in Figure 5. Transformer configuration must be YY (wye-wye).

In Figure 5, the meter is powered from the potential transformers that are fed from a breaker within the 600Y/347V panel. The CT cable is connected to the shorting enclosure before connecting to the CTs in the panel.
