Answer / Sandeep Kumar Jaiswar

Breakdown voltage (BDV) and breakdown current (BDC) can be determined using specific testing methods for VCB and CT devices. These tests measure the voltage or current at which a dielectric material begins to conduct abnormal amounts of electrical current, causing a breakdown. Consult the device manufacturer's documentation or standards such as IEC 60270 and ANSI/IEEE C37.010 for more information.
