AVO Training - Importance of Circuit Breaker Maintenance

Importance of Circuit Breaker Maintenance. Reliability of the power system can only happen when proper maintenance is applied to the equipment within the system. Insulation Resistance Tests. When running the insulation resistance tests, we must also take a temperature reading to apply a temperature correction because resistance is very temperature sensitive. Contact Resistance Tests. An important part of circuit breaker maintenance is the conductivity of the current path. For this we apply a device called a MICRO-OHMMETER or DLRO, which stands for a Digital Low Resistance Ohmmeter. Over-potential test (HI POT) Over potential tests are performed on the breaker in the same fashion as the insulation resistance tests. These tests are more likely to be used on medium and high voltage breakers.
