Distance protection is now available in the BE1-11f and BE1-11t versions for feeder and transformer protection applications. The Distance (21) elements offer protection that’s easy to coordinate when ...
Abstract: This paper presents comparative evaluation of the distance relay characteristics for UHV and EHV transmission lines. Distance protection relay characteristics for the EHV and UHV systems are ...
A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, ...
Abstract: With the increase in the number of STATCOM type FACTS devices in transmission lines, operation of distance relays in transmission lines are affected. It is very important that the distance ...
Tests of distance relay teleprotection schemes should check both relays simultaneously, including their communication link. This video shows a real test of a 110 kV overhead line. The protection was ...
Insulation resistance testers, often called megohmmeters, are fundamental tools for preventive maintenance, used to assess ...
