The importance of testing circuit breakers. Circuit breakers may remain idle for several years, but if a fault occurs, a large kiloampere fault current must gradually separate within a few milliseconds. The main errors that occur on circuit breakers are incorrect behavior, coil short circuits, mechanical connection damage/wear, or insulation materials. Therefore, it is necessary to regularly and carefully test the circuit breaker. Circuit breakers play a crucial role in protecting expensive equipment from fault damage by reliably connecting and disconnecting power sources; This requires on-site testing during installation and regular maintenance testing during its service life to demonstrate its reliability, in order to prevent costly faults and even issues that may endanger the safety of the substation. Therefore, regularly testing the performance of circuit breakers is an essential and cost-effective part of any maintenance strategy. The testing items of circuit breakers include vacuum degree, performance testing, high and low temperature resistance, combustion performance, contact pressure, mechanical characteristics, aging test, dielectric test, corrosion test, explosion-proof test, flammability test, service life, etc
