Wireless Model for High Voltage Direct Current Measurement using Hall Sensor

Abstract

Recent two decades watched the shifting trend from the energy resources conventionally available to modern renewable energy resources. In our surroundings, the amount of direct current based systems has also increased. Executions of the renewable energy sources; efficient as well as effective control need to be devised. For this purpose, an accurate measurement of high and low Direct Current is required. High Direct Current sensor and the measurement system using Hall sensor is developed which is presented in this paper. The Hall Effect Sensor receives the magnetic field in a loop of fused silica-fiber around the current-carrying conductor wire and measures the path integral of the magnetic field. By using this technique, the current can be accurately measured regardless of the asymmetric magnetic field distribution. The Fiber gyro technology sensor was employed to sense signals and for processing. This fiber is completely enclosed in a flexible strip which can be installed easily. The sensor which is proposed in the work has accuracy within 0.1% over a wide range of currents and temperature. It is determined with experimental results that the High-Voltage DC sensors and the measurement system proposed in this research are working correctly with acceptable accuracy.
