A relay is a protecting device used for protection of power systems such as machines, transformers, and generators etc. as it isolates the system from the fault condition in order to prevent damage from electrical overloads such as damage from high rated current and voltages. In order to protect the equipment from high voltages and fault currents relays are used to isolate the equipment from the system.
Relay sense the input voltage if it reaches the peak voltage called threshold limit it controls the input voltage if the input voltage exceeds the peak voltage limit it will trigger a signal to circuit breaker. Circuit breaker is a device used to make or break the circuit from the live to protect the complete system from short circuits.
Industrial relays are essential to protect the equipment in the system. Several relays operate in industrial applications such as SSR solid state relay, Electro-mechanical relay, overload protection relay, latching relay and other relays. Solid state relay (SSR) switching is completely electronic base where as in electromechanical, operation completely based on opening and closing moving contacts by a magnetic force. Solid state relays are familiar and most popular.
They are gaining attention from industries and witnessing a high growth opportunities in the global industrial relays market. In industries motors, generators, transformers, are running continuously those needs a protecting devices VCB, SF6, all needs a protecting devices to ensure the health of the equipment and to protect the complete power systems.
Relay triggers under faulty condition means in abnormal fault condition if not eventually the system get affected and damaged it even may damage the other machines if it is not isolated from the circuit.
