Why should AC power be switched on first for relay protection
A trickle-charging AC-to-DC power supply keeps the station battery in a constant state of full charge while AC power is available. In the event of an AC power interruption, all protective relays and other critical instrumentation in the facility will continue to. 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. The selection and applications of. Relion protection and control relays for several application reduce complexity. This guide explains the types, uses, and applications of relays to make your selection and. Protection is the branch of electric power engineering concerned with the principles of design and operation of equipment (called 'relays' or 'protective relays') that detects abnormal power system conditions, and initiates corrective action as quickly as possible in order to return the power. Activation of the relay's low-power signal triggers the energization of an electromagnet, initiating the movement of an armature.
