A protection relay is an electronic device that receives inputs in the form of current, voltage, temperature, or resistance and compares them to set points and provides outputs. Outputs can include visual feedback in the form of indicator lights and/or an alphanumeric display, alarms, communications, control warnings, and turning the power off and on.
A relay is a type of switch that can be operated both electrically and manually. It is used to control one electrical circuit by opening and closing the contacts of another circuit. A relay is made up of an electromagnet and a set of contacts. The mechanism of switching contacts takes place with the help of an electromagnet.
