High-Precision Traveling Wave Fault Indicator
High-precision traveling wave fault indicator (JYL-FL) consists of sensor unit, collection unit and backend system. The fault indicator monitoring terminals are deployed at various nodes along the lines. The device is equipped with local SIM cards for wireless communication using DES encryption algorithm to ensure data security. It adopts AI automatic diagnosis, eliminating the need for manual operation and maintenance. Intelligent management platform enables remote configuration of terminals, fault statistics analysis, and visual display of line routes.
