5.4.6 SENSITIVE GROUND CURRENT
The F650 Sensitive ground Current menu incorporates the following overcurrent elements:
•
Sensitive ground time overcurrent (51SG)
•
Sensitive ground instantaneous overcurrent (50SG)
•
Isolated ground overcurrent (50IG)
•
Sensitive ground directional overcurrent (67SG)
5.4.6.1 SENSITIVE GROUND TIME DELAYED OVERCURRENT ELEMENT (51SG)
Sensitive Ground TOC is a sensitive ground time delayed overcurrent protection element with a setting range 0.005A to
16A. The sensitive ground current input quantity is measured from the sensitive ground input, terminals B11-B12, and it
may be programmed as fundamental phasor magnitude or RMS magnitude as required by the application. The element trip
can be time delayed using a selectable curve. And it incorporates a reset time selectable between instantaneous or linear.
