Abstract

Among several switchgear equipment largely used in high voltage Transmission systems, which change the grid
configuration, isolates faulty parts from the grid, etc. circuit breaker is a remarkable one. For the reason to analyse the
interrupting capabilities, a circuit breaker has to undergo various test duties according to IEC 62271-100 among which
Test duty T100a is considered as the most onerous one. During this test the breaker has to prove its Interrupting capability
during maximum arc energy condition. This article focuses on the Performance evaluation of circuit breaker under
asymmetric condition Test duty T100a.
