Network protector control for spot network fed from feeder sources having voltage differences

A method of controlling a network protector for a spot network having a first feeder branch and a second feeder branch, the network protector including a circuit breaker and a network protector relay coupled to the circuit breaker, the method comprising:

• controlling operation of the circuit breaker from the network protector relay based on network protector relay non-sensitive trip settings, wherein the controlling includes causing the network protector to remain closed when:
• (i) an angular difference (±) between a transformer phase-to-neutral voltage of the first feeder branch and a transformer phase-to-neutral voltage of the second feeder branch is less than or equal to a first threshold value, and (ii) a magnitude difference (±) between the transformer phase-to-neutral voltage of the first feeder branch and the transformer phase-to-neutral voltage of the second feeder branch is less than or equal to a second threshold value.
