What is an Electromagnetic Relay ?
Electromagnetic Relay Definition
An electromagnetic relay is a switch that uses an electromagnet to mechanically operate a switching operation, essential in various electrical protection systems.
Operation Principles
The working of electromagnetic relays involves principles like magnitude and ratio measurement, essential for understanding their functionality in electrical systems.
Types of Relays
Attracted Armature type relay
Induction Disc type relay
Induction Cup type relay
Balanced Beam type relay
Moving coil type relay
Polarized Moving Iron type relay
Induction Disc Operation
Induction disc relays generate motion and operate based on the interaction of magnetic fields and a rotating disc, a key component in energy measurement.
Relay Applications
Electromagnetic relays are crucial in managing electrical circuits by providing over-current protection, voltage regulation, and system stability.
