Medium voltage circuit breakers play a very important role in medium voltage switchgear( metal clad, metal enclosure,…), and operating mechanism electrical and mechanical components functional tests is one of the most important tests for circuit breakers in panels. In this article, we have tried to talk about these tests briefly and in a list. Functional & operational tests are part of the routine and pre-commissioning tests for medium voltage circuit breakers. For more information about the seam of these tests, refer to the standards related to medium voltage switchgear like IEC 62271-200, IEC 62271-100, IEC 62271-1. The main objective of the test […]
