Diverse Protection Functions: It has multiple protection functions, including over – current protection, earth – fault protection, differential protection, frequency and voltage protection, etc. The differential protection is used for low – level internal faults, with the second and fifth harmonic restraint for magnetizing inrush and over – excitation. The earth – fault protection provides low and high impedance protection functions against winding earth faults.
High – precision Measurement: Adopting advanced digital signal processing technology, it can accurately measure electrical parameters such as current and voltage, and real – time monitor and analyze the parameter changes to ensure the safe operation of the power system.
User – defined Logic: The program logic can be prepared with a graphical tool for specialized applications, which is convenient for users to set according to actual needs.
Breaker Failure Protection: In case of breaker failure, it can respond quickly and trip the surrounding breakers to minimize the impact of faults.
Good Communication Capability: Support multiple standard communication protocols, which can be easily integrated into various power system automation systems to realize remote control and monitoring.
Application Scenarios
Power Generation Plants: Used to protect generators, transformers and related equipment in power generation plants, ensuring the stable operation of the power generation system.
Power Grids: Applied to the protection of lines and equipment in the power grid, which is helpful to maintain the stability and safety of the power grid and quickly isolate faults when faults occur.
Industrial Power Systems: In industrial power systems, it can protect factory equipment, motors and power distribution systems, and is suitable for various industrial occasions such as chemical plants, steel plants, and cement plants.
Renewable Energy Systems: In wind power and solar power generation systems, it can be used to protect inverters and equipment connected to the power grid, and cooperate with other devices to realize the stable operation of renewable energy power generation and grid – connection.
Railway Electrification Systems: Play an important role in railway electrification systems, ensuring the safe and reliable operation of the electrification system.
