Analysis of Non-invasive Low-voltage Electrical Fault Monitoring Measures and Device Selection
The article introduces non-invasive low-voltage electrical fault monitoring and analyzes several common types of low-voltage electrical faults,such as excessive contact resistance,line overload,short circuit problems,and leakage faults.Subsequently,measures for monitoring these faults were proposed,including fault signal extraction methods,wavelet analysis algorithms,signal singularity detection,and the overall architecture of the monitoring system.Finally,corresponding device choices were recommended for different monitoring needs,providing practical technical references for non-invasive low-voltage power fault monitoring.
