  • Overcurrent protection voltage value of relay protection

    Overcurrent protection voltage value of relay protection

    Voltage restrained overcurrent protection provides improved sensitivity of overcurrent relaying by making the set overcurrent operating value proportional to the applied input voltage. The overcurrent relay is used to protect the alternator or generator against overloading and which trip the circuit breaker. The short circuit creates heavy fault current through the winding for few milliseconds. The principle is to grade the operating times of the relays in such a way that.
