Feeder protection relay is a device used for feeder protection, F650-G-N-A-B-F-2-G-1-HI-C-E is mainly used for line protection of power systems. The relay can carry out over current protection, quick break protection, over voltage protection and under voltage protection to ensure the safe and stable operation of the line.

The working principle of feeder protection relay is based on the detection and control of electrical parameters such as current and voltage. When there is a fault in the line, the relay automatically detects the fault current and compares it according to the set value, and then performs the corresponding protective action according to the fault type, such as cutting off the fault line or sending an alarm signal.

The feeder protection relay has the characteristics of high reliability and fast response, which can act quickly when the line fails, avoid fault expansion and reduce the damage to the equipment. At the same time, the relay also has the advantages of easy maintenance and debugging, and can be adjusted and expanded according to the actual needs.

In short, F650-G-N-A-B-F-2-G-1-HI-C-E feeder protection relay is one of the important equipment in the power system, which can realize the comprehensive protection and control of the feeder and improve the reliability and stability of the power system.

Feeder protection relays have a variety of primary functions to ensure the safe and stable operation of the power system. Here are some of the main functions of feeder protection relays:

Overcurrent protection: When the current in the line exceeds the set safe value, the feeder protection relay will cut off the line to prevent equipment damage caused by excessive current.

Quick break protection: In the event of a serious fault, such as a short circuit, the feeder protection relay will quickly cut the line to prevent the fault from expanding.

Overvoltage protection: When the voltage in the line is too high, the relay will activate the protection mechanism to prevent the equipment from being damaged due to overvoltage.

Undervoltage protection: When the voltage in the line is too low, the relay will also take protective measures to ensure that the equipment will not be damaged by undervoltage.

Time overcurrent protection: When overcurrent is detected in a specific period of time, the relay will take the corresponding protective action.

Automatic reclosing: In some cases, such as transient failures, the relay can automatically re-close after a certain time to try to restore the normal operation of the line.

Frequency protection: For changes in the frequency of the power grid, the relay can set the corresponding protection strategy.

Automatic reclosing option: The automatic reclosing function can be opened or closed according to the actual situation.
These functions work together, so that the feeder protection relay can comprehensively monitor and control the operating status of the power system, find and solve potential problems in time, and ensure the stability and reliability of the power system. In practical applications, feeder protection relays with corresponding functions can be selected according to specific line characteristics and requirements.
