Design on High Voltage Power Supply of Fiber Current Transformer

According to the power supply of high voltage of fiber current transformer, reached on several schemes of power supply. Then the power supply system of fiber current transformer adapted to small current measurement, that is, combined solar energy and storage cell. This scheme has the virtues such as steady operation, immune to power network wave compensation and electromagnetism, low noise. Importantly, this scheme solved the problem of huge busbar current and dead band current. The experiment results indicated this scheme is high precise and strong antijamming. So this scheme can supply power for high voltage signal process system successfully.
