In recent years, it has become increasingly important to consider distributed resources, high efficiency operation and maintaining power quality in the distribution network. It is necessary to utilize the measured value of the network voltage and current in order to plan, operate and control the distribution network. Therefore progress in monitoring sensor technology is also needed.<br>Many monitoring sensors for voltage and current of distribution lines have been studied and developed. Almost every type of existing sensor uses a photo device for sensing voltage and current. These are sensitive to leaking resistance of the surface of the sensor case and optical fiber cable for signal transmission.<br>In this paper, we propose a new sensing method for the phase voltage of distribution lines that is robust in terms of the leak resistance of the surface of the case and of the covered wire. A comparison of equivalent circuits between the proposed method and an existing method, the development of the prototype, and the result of a field examination are also described.
