Air/gas circuit breakers - Megger

sf 6 circuit breakers suffer less wear on the main contacts than do air and oil circuit breakers. The breaking principle is to cool down the arc by blowing Sulfr hexafluoride gas with high pressure towards the arcing contacts. An Sulfr hexafluoride circuit breaker’s arc extinction method may be characterized as either puffer or self-blast.Get price

3 Basic Electrical Tests for Medium-Voltage Circuit Breakers

EffectsSafetyOperationPerformanceUsePurposeSignificanceWhen a fault occurs on the electrical power system, fast and reliable protection means everything.

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.
