A new design of an Electronic Protector for Single Phase Electrical Equipments
By Abdulkareem Mokif Obais
Abstract:
This protector is designed of simple and discrete electronic devices. No transformer is used in the electrical circuit, so the lumped set will be of small size, light weight, and cheap. The power consumed by the electronic circuit and the relay used is less than 15 Watts. When the phase voltage of the power system is in the range of (199-241) Volts r.m.s value, the protector connects the load to the power system network, unless otherwise the protector will disconnect the load from the power network.
