Connection Settings for Current Differential

When the zone of protection includes a transformer, it may be necessary to provide phase angle and zero

sequence compensation to the currents used by the Phase Current Differential Protection (87) element.

See Figure 271 and Figure 272. For each input circuit, a setting is provided to enter the transformer

connections associated with that input.
