Abstract
This paper proposed a new fault detection method of short circuit of the primary side of TA applied to high voltage electric power metering system. Firstly, through theory analysis we obtained the close relationship between network impedance and short circuit of the primary side of TA. Secondly, we designed the method of fault detection to research and analyze the fault signal. Lastly, we obtained a plan that is feasible in practical application.
