AI Technical Summary

Benefits of technology

This new technology helps identify small electrical failings quickly by injecting waves into an electricity network accurately without requiring manual inspections or human interference from outside sources like wires that may have been damaged during maintenance operations. It also includes combining radio signals with timely communications capabilities to help workers locate their problem more efficiently while minimizing downtime caused by power failure events. Overall this innovation enhances safety measures and reduces economic losses associated with power disruptions.

Problems solved by technology

This patented technology solves issues with finding accurate and efficient way to locate and fix single phase grounded (SPG) faults that could lead to damage or even failure of critical sections within the electric utility company's main transmission area. Current methods are time-consuming and require significant effort from skilled workers who often take longer hours before identifying any potential locations of these fault points.

Abstract

The invention provides a low-current single-phase earth fault line selection and localization device. The device comprises a host, a bus PT and at least one set of sensors, wherein the bus PT is used for collecting bus three-phase voltages of a power distribution network system. Each of the sensors includes a bus outlet sensor, three branch sensors and a wireless sending unit; the bus outlet sensor and the three branch sensors are respectively connected with the wireless sending unit. The host comprises an operation control unit, an earth fault monitoring circuit, a wavelet signal emitter and a wireless receiving unit, wherein the earth fault monitoring circuit, the wavelet signal emitter and the wireless receiving unit are respectively connected with the operation control unit; the earth fault monitoring circuit is connected with the bus PT; the wavelet signal emitter is connected with a neutral point of the bus PT; and the operation control unit and the sensors carry out wireless communication. According to the invention, trouble of manually searching of a fault point along a line according to a previous method can be saved; and the device has advantages of accurate fault determination, high line selection accuracy and rapid fault localization.
