What is the normal current for relay protection
If the relay is rated with 1 A, the normal pick up current of the relay is 1 A and it should be equal to secondary rated current of current transformer connected to the relay. The current setting is sometimes referred as current plug setting. The limit is defined by the electrical load (burden) of. Selectivity is a mandatory requirement for all protection, but the importance of it depends on the application. For example, unselective protection operation during a medium voltage network fault will cause an outage for an unnecessarily large number of consumers. In this post, we will understand these types of protection relays. These types of devices protect electrical systems and components from damage when an unwanted event occurs, such as an electrical. 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 system continue to run under normal conditions.
