The major functions of this monitoring system include the detections of overload temperature, impending cable fault, and accurate fault location. Accurate fault detection and location can prevent the reclosing of the circuit breaker installed in the substation. Junction temperature is a crucial parameter of power-switching semiconductor devices, which needs monitoring to facilitate reliable operation and thermal control of power electronics circuits and ensure reliable performance. Unlike traditional electrical temperature measurement (thermocouples & RTD), the length of the fiber optic cable is the temperature. The FA-M3V Edge Controller is directly connected to a thermal camera to deliver cost-effective computation and decision processing using a general-purpose controller, which integrates well with host systems. It can also be used with Data Logging Software GA10 to enable extended data storage. Furthermore, these devices are subjected to repetitive heat pulses due to high-frequency switching, which leads to the junction.
