Electrical engineering root cause analysis (RCA) related to poorly built Switchgears and Why do breaker parts tear apart or don’t work?
Oil circuit breakers are the oldest type of circuit breakers. The separating contacts of the oil circuit breakers are made
AC type protective relays are actuated by the current and voltage supplied by the current and potential (voltage) transformers which
In Electromagnetic relays operating current flows through the coil. When this operating current increases, coil energizes the electromagnet. When the
Generally on neutral grounding is provided at each voltage. There will be several voltage levels between the generation of the
Step Potential Step potential is the step voltage between the feet of a person standing near an energized grounded object.
What are the functions of protective relays To detect the fault and initiate the operation of the circuit breaker to
