Circuit Breaker Testing
Manufacturers and end users of circuit breakers carry out rigorous evaluations to certify their product's quality and effectiveness. These evaluations include assessing the strength of insulation and integrity of contact resistances, which are critical for safety and performance.
The circuit breakers' electrical and mechanical operations dependability is ascertained by conducting trip and close coil examinations. Analysis of operational timing is also performed to ensure proper sequence and timing of operations. Further, tests involving high currents are executed to guarantee the safe interruption of fault currents.
Moreover, those utilising these circuit breakers undertake consistent maintenance checks, encapsulating all previously mentioned tests. These checks guarantee sustained optimal performance and uncover any latent issues or malfunctions that might have surfaced over time, thus allowing for prompt resolution.
OEM TestingCrest has engineered its CB test system range, ensuring it caters to the ongoing operation demands and maximum uptime prerequisites of Original Equipment Manufacturers (OEMs). These systems are accompanied by bespoke test software capable of generating secure, unalterable test reports in formats tailored to the user's preferences. Moreover, we offer a variety of additional tools and features customised to meet the unique requirements of each application, ensuring a comprehensive, user-oriented solution.
On-Field TestingCrest has established a line of portable CB test systems specifically designed for testing circuit breakers up to 800kV, typically found in switchyards. These systems have undergone rigorous type-testing and have demonstrated their resilience in the challenging conditions often present in switchyards. Moreover, our analysers have valuable additional features, such as dynamic contact resistance meters and travel transducers, with custom-engineered fixtures. This combination ensures dependability and versatility, making our systems robust and user-friendly.
