摘要： The present invention provides an online monitoring circuit of the series compensation spark gap divider return circuit. Said series compensation spark gap divider return circuit includes a voltage equalization link and a voltage sampling link. Said voltage link includes the capacitor C which series said voltage equalization link. Said online monitoring circuit includes the voltage sampling input module, series compensation current input module and the compare module. Said sampling voltage input module after amplified the voltage of the two ends of the series capacitor C converts it into direct current signal.
