| Abstract: | In the paper, at first we analyse the common failure and the cause of failure of 6-10kV high voltage motor.and then, we put forward the analysing methord of the failure of motor, adopting the measuring of positive and negative sequence current. We also expound the principle of hardware and the design of software of single chip microrprocessor protectng on device.The device has following functions: protection of short circuit; protechon of unbalance; protection of grounding and protection of over-voltage and under-voltage, |
