4.7.7 PHASE DIFFERENTIAL

These setpoints program the differential element when the differential feature is in use. This feature consists of
three instantaneous overcurrent elements for phase differential protection. Differential protection may be con-
sidered first line protection for phase to phase or phase to ground faults. In the event of such a fault, differential
protection may limit the damage that may occur.

Care must be taken when enabling this feature. If the interrupting device (contactor or circuit
breaker) is not rated to break potential faults, the feature should be disabled. Alternately, the
feature may be assigned to an auxiliary relay and connected such that it trips an upstream
device that is capable of breaking the fault current. A low level differential fault can develop
into a short circuit in an instant. 

A trip occurs once the magnitude of either

 (phase differential) exceeds the

Pickup Level 

×

 Differential CT Primary for a period of time specified by the delay. Separate pickup levels and

delays are provided for motor starting and running conditions.

The Differential trip element is programmable as a fraction of the rated CT. The level may be set more sensitive
if the Differential CTs are connected in a flux balancing configuration (3 CTs). If 6 CTs are used in a summing
configuration, the values from the two CTs on each phase during motor starting may not be equal since the CTs
are not perfectly identical (asymmetrical currents may cause the CTs on each phase to have different outputs).
To prevent nuisance tripping in this configuration, the 

STARTING DIFF. TRIP PICKUP

 level may have to be set less

sensitive, or the 

STARTING DIFF. TRIP DELAY

 may have to be extended to ride through the problem period during

start. The running differential delay can then be fine tuned to an application such that it responds very fast to
sensitive (low) differential current levels.
