Maintenance Programs for MV HV Power Circuit Breakers - zensol

PrefaceIntroductionDescriptionThis article is the first in a series of articles that will help to bring light to the maintenance practices presently applied to power circuit breakers. A list of the most popular tests used; with reference to the international standards compliance, is included at the end. Each test provides a bit of information that is complementary to the others, providing a general overview of the circuit breakers testing practices. A circuit breaker is an important equipment to power electric networks. Its importance is due to the protection role it is playing. Hence, it is imperative to assure its proper operation. This is only possible by applying suitable maintenance. The main purpose is to help us understand, accurately, the real condition of the breaker being tested thus helping targeting the corrective actions. This targeting helps minimize maintenance spending and increase network reliability, hence leading to efficient network management.Get price
