Zusammenfassung: | The invention relates to a repair point reporting system for local electric leakage of a high-voltage switch cabinet. The system comprises computer information processing equipment, information receiving equipment and a filter, the filter is in signal connection with the information receiving equipment, the information receiving equipment is in signal connection with the computer information processing equipment through a transmission line, and the filtering efficiency can be measured by the insertion loss (IL) of the filter. it is defined that WL = 20 1gE1/E2 (db), E1 is the voltage generated by the leakage signal on the load impedance or the receiver when the leakage signal is not filtered, and E2 is the voltage generated by the leakage signal on the load impedance or the receiver after the leakage signal is filtered, the power line is detected through the filter, and the power filter has a low-pass characteristic, so that direct-current or low-frequency power is transmitted without attenuation.
