Although fault location schemes for distribution systems are well-established, the branching nature of rural 11 kV networks can often result in areas where existing substation-based fault locators are unable to give accurate results. RAFL system will provide utilities with significant time savings in investigating the cause of intermittent and problematic arcing faults.
Engineers from Elimpus are entering the trial phase of an EIC funded project to develop a system utilising the reception of arcing fault radio signals to locate the position of the fault. To achieve this, several monitoring stations poles will accurately time the arrival of the arcing fault radio. Each monitoring station will upload both its position and the signal arrival time to a cloud server. A specially designed application running on an internet-enabled laptop will convert the data from up to 4 monitoring stations into the ground position of the arcing fault in real-time, allowing utility engineers to access the data in the field.
