Why CBCT is used in electrical? CBCT is used in motor protection for providing Zero sequence protection. The core of core- balance CT surrounds the power cable connected to the induction motor. The earthing lead from the cable-sheath to earth must be taken through the eye of the CT core.

How do you choose a CBCT ratio? Choose the ratio of the CBCT to to provide lots of current on the maximum fault current. For instance if your maximum ground fault current is 20A and your relay can take 20A continuously, you could go as low as a 5:5 CBCT. The lower the ratio, the lower the minimum fault current that can be detected.

What is a core balance earth leakage relay? Earth leakage relays monitor the leakage of current to earth on 3 phase electrical systems.
