RELAY

The current transformer is used to step down the higher current in the primary and protects the measuring instruments against high currents. Low Voltage Transformers are used for supply to measuring instruments & protection devices of electrical switchgear and control gears installation. They are suitable for system voltage 415/660V & Frequency 50/60 Hz. These Current Transformers are designed for a secondary current of 1A or 5A and a primary current ranging from 5A to 7500A depending on the application of the system load current. Analog Meters are used in panels to measure electrical parameters like current, voltmeter, power factor, frequency, etc. They display values on a dial, usually with a moving pointer or needle. A relay that has contacts that operate when the voltage drops below a set voltage. Undervoltage relays are used for protection against voltage drops, to detect short-circuit faults, etc. The main function of the relay is to sense or detect the abnormalities in the circuit and to send a message to the circuit breaker to break the circuit. In the case of an under voltage relay if the voltage in the circuit or system is less than prescribed value it will disconnect the circuit with the help of a circuit breaker.
