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.

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.
