Overview
The “Phase time overcurrent” element can provide a specified time-delay operating characteristic versus the applied current or be used as a simple definite time element. The phase current input quantities can be programmed as fundamental phasor magnitude or total waveform RMS magnitude as required by the application.
For more detailed information on “Phase time overcurrent” element, refer to GE, Universal Relay (UR) family of products, Version 8.0x manuals.
