Protective relays and devices have been developed over 100 years ago to provide “last line” of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of
suffix letter or number may be used with the device number; for example, suffix N is used if the device is connected to a Neutral wire (example: 59N in a relay is used for protection against Neutral
The relay is also used as back-up protection in applications, where an independent and redundant protection system is required such as in transformer protection. Depending on the preconfi guration
