THOMPSON KNOWS BREAKER TESTING & COORDINATION
Circuit breakers are designed to work reliably for years.
The problem is that circuit breakers fail when you need them to work because
they have not had the proper testing, coordination, and maintenance. The
experienced team at Thompson Automation and Specialty Services understands the proper testing,
coordinating and maintaining of circuit breakers and keeping equipment,
facilities and personnel safe.
Circuit breakers are very important for the proper function
of power supply systems, being responsible for effectively opening and closing
the circuit to remove faults and connect/disconnect parts of the network. They
are built to withstand considerable static and dynamic workloads during their
lifecycle, which can be several decades. They have to perform its duty after
months or years of inactivity, therefore the circuit breaker testing is
essential to ensure its function properly and optimize network reliability.
Circuit breaker testing can be done at various stages in the life of the circuit breaker, in
production, commissioning, maintenance, fault troubleshooting, etc.
Circuit breaker testing is intended to predict an abnormal operation before it happens, saving time and money. High measurement accuracy is required for circuit breaker testing, but we Thompson Automation and Specialty Services also understand the importance of limiting your down time while the testing is taking place. We strive to keep the time that the circuit breaker is out of service short. Close and trip times, synchronism, trip & close coils condition, mechanical motion analysis and status of the DC batteries are the most commonly checked parameters in circuit breaker testing, since a large part of the major failures have mechanical origin.
