Protective relays and devices have been developed over 100 years ago to provide “lastline”of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of

The proposal itself and define the different protection zones should be based on impedance lines to be determined by the calculation referred to in the previous section of this article.
