Research on Substation Leakage Current Detection Device Based on Wireless Synchronous Communication

Abstract

The substation power supply system is the key to ensuring the safe and stable operation of the substation. The leakage current in the cable may cause serious accidents such as channel fires. The traditional detection device cannot distinguish the leakage current and the unbalanced current in the circuit. Aiming at the accurate detection of leakage current in the station power system, a new leakage current detection device for the station power system is developed in this paper. The device is composed of multiple wireless acquisition terminals, with multi-channel synchronous acquisition, automatic data communication, current vector, and calculation functions. The device can realize the accurate detection of leakage current and the accurate positioning of defects in the substation AC system. And it can quickly, effectively, and accurately detect the operation of the station AC system, with high economy and practicality, which is helpful to ensure the safe and stable operation of the substation.
