Description

technical field [0001] The invention relates to circuit line loss monitoring technology, in particular to a circuit line loss comprehensive monitoring device. Background technique [0002] Power line loss is an important indicator of power quality, and the power departments at all levels attach great importance to it. Timely detection of electricity stealing users and metering faults is the main content of circuit line loss monitoring. At present, the circuit line loss monitoring is mainly carried out by the following methods: On the one hand, by installing a metering AC sampling device on the user terminal for comparison and analysis, and thus discovering electricity-stealing users. On the other hand, metering faults are found through manual inspection. Practice has shown that this circuit line loss monitoring method is limited by its own principles. On the one hand, there is a problem of incomplete data collection; This results in excessive labor costs. Contents of th...
