Analyze the line fault. Second in capacitor, MOV, trigger the gap in this paper, based on the principle of damping reactor, the analysis and research is mainly focused on the fuse outside internal fuse capacitors and capacitor and its advantages and disadvantages, pointed out the influence of fault capacitor element for distributed voltage; Analyzes the MOV, trigger interval, the action of the bypass circuit breaker, draw a series compensation device on the discharge Gap Gap on voltage, MOV on current and the energy of the MOV waveform. And put forward the limit on capacitor group overvoltage, protect the capacitor set of measures, further to the operation of the series compensation device correctly and the control met
