The relay protector is an automatic device, ABB-REF620E_F-NBFNAANNNCC1BNN1X, used to detect and respond to abnormal conditions in the power system, thereby protecting the system from damage. Its working principle is based on a set of logical rules, when a fault or abnormal condition in the power system is detected, it will trigger the corresponding action, such as disconnecting the fault part, to prevent the fault from expanding or causing further damage to the entire system.

The main functions and features of the ABB-REF620E_F-NBFNAANNNCC1BNN1X relay protector include:

Fault detection: The relay protector can monitor the operating status of the power system in real time, including current, voltage, frequency and other parameters. When abnormal or fault conditions are detected, such as short circuit, overload, ground fault, etc., it responds immediately.

Fast action: Once a fault is detected, the relay protector quickly cuts the connection between the faulty part and the system to prevent the fault from expanding or causing more serious consequences. This quick action minimizes the impact of faults on the system.

Selective action: The relay protector is selective, that is, it will only cut off the faulty part without affecting other normal parts of the system. This ensures that the rest of the system can continue to operate normally, improving the reliability of the system.

Sensitivity: The relay protector has a high sensitivity to fault detection and can accurately distinguish between fault and normal operation. This ensures that in the event of a failure, the relay protector can make a timely and correct response.

Automatic reclosing: Some advanced relay protectors also have an automatic reclosing function, that is, the ability to automatically attempt to reconnect the system to restore power after a failure occurs. This improves system availability and continuity of power supply.

Relay protectors are widely used in various parts of power system, such as generators, transformers, transmission lines and so on. ABB-REF620E_F-NBFNAANNNCC1BNN1X is one of the important equipment to ensure the safe and stable operation of power system. The reliability and power supply quality of the power system can be improved effectively through rational configuration and use of relay protectors.
