Electricity is one of the key energies that is driving almost every automated device from household daily life gadgets to heavy instruments driven in the industries. Electricity is distributed from power plants to the industries and to the house through transmission lines. Electricity drives any electrical equipment in the presence of alternating (AC) voltage and current. AC voltage drives the AC current to flow through the wire and drive the equipment. But due to internal faults in wire, the current cannot come out of the power plug where the devices to be driven need to be connected. In such cases of faults, the best way is to detect the presence of voltage in power plug is to put an electrical tester in the plug point. But this technique of detecting the presence of voltage at the power point plug could be dangerous for life if is it is mishandled by untrained person. Hence in this paper a wireless, non-contact voltage tester has been proposed that can proved to be an instrument safe for human life specially for the persons who are not trained at all.
