Circuit Breakers are one of the critical “safety-valves”of electrical systems and basic maintenance procedures are essential to maintain maximum reliability.
According to the actual situation of the DC circuit breaker ampere-second characteristic test system, our company has introduced a DC circuit breaker ampere-second characteristic test system suitable for substation site use, easy to carry, and high degree of automation. It can provide DC protection for the operation and maintenance department. Characteristic testing methods are used to verify the action characteristics and level difference coordination of DC protection appliances, to improve the reliability of the DC system operation and ensure the safe and reliable operation of the power grid.
