A power relay is similar to a switch but is designed to control high-voltage or high-current circuits using a low-voltage signal. It functions by using an electromagnetic coil to open or close contacts, allowing it to act as an automated switch. This makes relays essential in applications like automotive systems, industrial machinery, and home automation, where they can safely control larger loads without direct human intervention.

What is difference between reverse power relay and directional relay in electrical protection?
A reverse power relay is a directional overcurrent relay. Directional relays are relays that sense power flow in one direction, and include (directional) overcurrent relays, reverse power, and impedance based relays. So a reverse power relay is a directional relay, but a directional relay is not necessarily a reverse power relay.
