Success Story: Preventing Circuit Breaker Failure At One Of India’s Largest Electric Power Transmission Utilities

As elaborated in our previous post, Dynamic Contact Resistance Measurement (DCRM) tests play a pivotal role in preventing unexpected failures of High Voltage (HV/EHV/UHV) Circuit Breakers by cohesively assessing the healthiness of their contacts. Widely considered as the most comprehensive CB testing methodology, the success of any DCRM test depends on a trifecta of the …

DCRM Testing For High Voltage Circuit Breakers: What, Why, How

High Voltage Circuit Breakers (HV/EHV/UHV) act as the most effective protection mechanism against electrical mishaps in the high voltage environment of Substations. Since Circuit Breakers (CBs) are mechanical devices, they are vulnerable to breakdowns if timely performance tests are not conducted to ensure their functional healthiness. In our earlier post, we broadly covered the 9 …
