What is the test for HV circuit breakers?

Regular preventive testing of high-voltage circuit breakers, including insulation resistance, dielectric loss factor, contact resistance, AC withstand voltage, vacuum level, mechanical characteristics, primary current injection, SF6 gas quality, and insulating oil tests, is essential to ensure their safety, reliability, and operational integrity, preventing faults that could compromise the power system.
