2. Eliminating dangerous operating conditions
2.1 General
Operating faults must first be detected and then eliminated. To detect them, we use protection relays that constantly monitor the evolution of various parameters of the network and the installations supplied 2.2 . These relays have one or more contacts which are activated to signal the anomaly and/or to give the order to eliminate it.
To make them more economical and easier to implement, relays operate at low voltages, generally less than or equal to 100 V, and with low currents,...
