Electromechanical Relays

The relay is an electromechanical switch used as a protecting device and also as a controlling device for various circuits, equipments, and electrical networks in a power system. The electromechanical relay can be defined as an electrically operated switch that completes or interrupts a circuit by physical movement of electrical contacts into contact with each other.

Numerical Relays

Numeric relays are the evolved form of a static and electromagnetic relay. They are basically a device used for measuring electric parameters in an electrical network and convert them into numerical data which undergoes mathematical and logical analysis to decide on tripping an electrical network.

The main purpose of a numerical relay is to protect the electrical network from unexpected fault currents. Numerical relays are mostly preferred because of their versatile characteristics. A single Numerical relay can monitor multiple parameters like current, voltage, Frequency, onset time, offset time, etc. And the same relay can be used for analysing and monitoring multiple faults such as over current, over fluxing, different current and more.
