Fault Indicator

The external signal-type power distribution line fault indicator is applied to the field of overhead line fault location. It is a power distribution automation product that integrates multiple technologies such as wireless radio frequency communication, low current power supply, and low power consumption. This product solves the problems of short-circuit fault detection of overhead lines and single-phase grounding positioning, and has the function of real-time monitoring of line load. Used in conjunction with a signal source, the signal injection method is used to greatly improve the accuracy of single-phase ground fault location. The collection unit has a suspended design and has a wide range of applications.
