Description

technical field [0001] The invention relates to the technical field of power monitoring, in particular to a fault alarm system and method for a low-voltage distribution network. Background technique [0002] The low-voltage distribution network is an important part of the power system. Whether the low-voltage distribution network can operate safely will have a direct impact on the life, work and production of users. It is the key to ensure the safe and orderly operation of the low-voltage distribution network to discover the faults in the low-voltage distribution network in time and take effective measures. [0003] At present, the monitoring of faults in the low-voltage distribution network mainly provides indirect feedback through the assessment table of the station area or the low-voltage meter. In view of the above-mentioned fault monitoring methods in the existing low-voltage distribution network, the following problems are faced: first, due to the insufficient data co...
