Protection Relays & Systems has become an integral part of the electrical power system, providing a high degree of protection and reliability for critical components. The SE-KP2N is a versatile and reliable protection device that provides fast and reliable operation in a wide range of application fields. In this article, we\'ll discuss the different application fields and working principle of the SE-KP2N.

The SE-KP2N is a powerful, lightweight, and highly reliable differential over-current relaying system designed for both motor protection and generator protection. It has the ability to detect small and large currents with sensitivity and accuracy. The SE-KP2N can be used in a wide variety of applications, including motor protection relay systems, generator protection relay systems, point-of-common-coupling protection, and arc-flash protection. The SE-KP2N is also ideal for measuring harmonics, providing overcurrent protection, and integrating with advanced control systems.

On the application field side, the SE-KP2N is well suited for motor protection in industrial factories, automobiles, and marine vessels. It is also well-suited for generator protection in critical power systems, such as power plants, hydroelectric plants, and wind farms. The SE-KP2N is also used in arc-flash protection in hazardous locations, such as chemical plants, refineries, and mining sites.

As far as working principle is concerned, the SE-KP2N is designed to detect both over-current and under-current conditions. It utilizes two separate trip contacts that can be set independently to either open or close the circuit. If either of the trip contacts is open, the over-current condition is detected, and the circuit is immediately opened. If the current exceeds the set trip level, it triggers the other contact to close, which trips off the circuit.

Moreover, the SE-KP2N features adjustable differential time delays, allowing users to customize the protection time of the system. By customizing the protection time, users can achieve a more accurate discrimination between correct operation and faults. The SE-KP2N also features a built-in minimum current algorithm to reduce any detected noise signals, providing a reliable protection solution.

The SE-KP2N is built with a wide range of accessories, such as ground fault detection, phase comparison, the fuse fail to trip, surge protection devices, remote control and monitoring, voltage levels, and harmonic distortion. These accessories extend the functionality of the SE-KP2N, making it an ideal solution for a variety of applications.

In conclusion, the SE-KP2N is a reliable and versatile protection system that can be used in a wide variety of application fields. The adjustable differential time delay and minimum current algorithm helps make it ideal for motor protection, generator protection, point-of-common-coupling protection, and arc-flash protection systems. With a wide range of accessories, the SE-KP2N makes it easy to customize the protection system according to the specific application.
