BEHAVIOR OF BUSBAR DIFFERENTIAL RELAYS WITH AIR-GAP CORE CURRENT TRANSFORMERS
… Then, two commercially available busbar differential relays with CT saturation detection logic were subjected to the output waveforms of solid-core and air- gap core CTs. After testing about hundred scenarios on each relay, it is concluded that first, there is no difference in the relays’ …
