Title:
SYSTEM FOR MONITORING ELECTRICAL POWER TRANSMISSION LINE
Document Type and Number:
WIPO Patent Application WO/2016/125028
Kind Code:
A8
Abstract:
A system for monitoring electrical properties of a power line includes a current sensor with a gapped core and a conductive winding, The system further includes output control circuitry coupled with the current sensor, and including voltage leads configured to provide an output voltage indicative of electrical current through the power line, to an intelligent electronic device (IED). A gas discharge tube is connected to winding leads of the conductive winding and to the output control eirciritry, and activated in response to real or simulated short circuit conditions, to protect the output control circuitry. Related methodology is disclosed.
