A New Type of High-voltage Fiber Optic Current Sensor

In this paper, the design idea and the operation principle of a fiber optic current sensor with a little power consumption supplied with solar cells is presented. The solar cells is used as the power of the detecting part of the current transformer, thus both of high voltage subsystem and low voltage subsystem are insulated each other. Not only it can the higher testing accuracy be maintained, but also has the advantages of small seize, long life, low price and so on. It is suitable to real time measure high voltage power current.
