Overview
The “Phase directional overcurrent” elements (one for each of phases A, B, and C) determine the phase current flow direction for steady state and fault conditions and can be used to control the operation of the phase overcurrent elements via the BLOCK inputs of these elements.
For more detailed information on “Phase directional overcurrent” elements, refer to GE, Universal Relay (UR) family of products, Version 8.0x manuals.
