Burden of a protective relay is the power______________?
Correct answer: B. absorbed by the circuit of relay
- A. required to operate the circuit breaker
- B. absorbed by the circuit of relay
- C. developed by the relay circuit
- D. none of the above
Explanation
Relay burden is the power absorbed by the relay circuit, usually expressed in volt-amperes at the rated current or voltage. It is not the power needed to operate the circuit breaker itself.
