Faults in medium-voltage distribution networks are usually detected using short-circuit and earth-fault indicators. The faster this happen, the quicker network can be restored. Efficient remote monitoring of the short-circuit and earth-fault indicators prevents time-consuming troubleshooting and inspection trips.
Solution
Short-circuit and earth-fault indicators such as Horstman’s Sigma D++ offer remote signaling contacts, but often they are not used at all. The 5G SENS GPIO can read the status of these potential-free permanent or wiping contacts and transmit their status to a cloud server. This makes it possible to locate the fault with pinpoint accuracy. With this data, the consequences for network customers can be minimized and eliminated as quickly as possible.
