Switchgear Functional Checks

 Switchgear functional checks are a crucial component of switchgear maintenance because they guarantee that the switchgear systems and components are functioning properly and serving their intended purposes. Check sure circuit breakers function properly and smoothly. Verify the breaker contacts make and break as expected by checking for correct closure and tripping actions. Check to see if the control circuits and trip coils are operating properly. Electrical circuit breakers, protective relays, and other protective devices are tested using a method called primary injection testing . In order to replicate a fault scenario and ensure that the protective devices are functioning properly, it entails injecting a regulated and calibrated current directly into the primary side of the circuit.  The primary purpose of this testing: Check the trip and timing details: Circuit breakers, relays, and other protective devices can have their trip characteristics and timing verified by prima...
