Abstract :
The fault location in electric energy transmission structures using polymeric insulators is difficult to protect, since there are no visible signs of usage. This paper presents a real time failure detection system in polymeric insulators using an electronic system that measures the eletric current escape. The system stores leakage currents on the log file at regular time intervals and sends data to a server through a system of wireless sensor networks (WSN). A backup system is responsible for analyzing the values of each structure and generates alarms if certain current values are exceeded. The system was validated in the field on a power company distribution network.
