The CT bore is 80 mm, which means a 25 mm minimum air clearance from 11 KV bus. It has been working fine for years but I am not comfortable with a
CURRENT TRANSFORMERS (CTs) Product specifications Current transformers (CTs) are used to convert high current values circulating in cables or busbars to current values permitted by
The high fault magnitudes increase the possibility of CT saturation during external faults close to the busbar, and CT saturation increases the possibility of an incorrect operation of the busbar protection.
Bus bar CT is available in 40 to 4000A with 1VA to 15VA burdern and 0.5 to 5% Accuracy
