Protection relays are used in electrical systems to detect protective conditions and disconnect faults. They are typically connected between the power source and the device being protected, such as an electric motor, generator, capacitor, or fuse. The purpose of protection relays is to detect unwanted currents, mitigate damages, and disconnect the fault as quickly as possible in order to maintain the electrical system\'s integrity and working order.

The 9-1618107-2 is a type of overvoltage protection relay. It consists of a voltage transducer, a power supply, and a control stage. The voltage transducer detects the voltage of the power system and passes the information through the control stage. If a certain limit of voltage is exceeded, or a sudden surge of current is detected, the control stage trips the relay, and the power system is disconnected.

The 9-1618107-2 has a wide range of applications in the field of protection relays. It is suitable for protection against overvoltage, overcurrent, short-circuits, undervoltage, and other overloads for all types of motor and transformer protection. It is also used in AC power systems with nominal voltage of 110kV or less, for the detection of high overvoltage during the testing of high-voltage transformers and capacitors.

The 9-1618107-2 operates on the principle of overvoltage detection. As Voltage across a certain point exceeds a certain set limit, it trips the relay and disconnects the power system. This prevents any serious damages caused by overvoltage, such as electrical components overheating and burning. The 9-1618107-2 is also equipped with overcurrent protection, so it can detect sudden surges of current and trip the relay quickly.

The 9-1618107-2 is suitable for a wide range of applications in the protection relay field. It can provide effective protection against overvoltage, overcurrent, short-circuits, undervoltage, and other overloads for all types of motor and transformer protection. Its overvoltage detection system ensures the safety of the power system and its components during testing and normal operation.
