Protection relays are essential components of electrical systems, with their primary purpose being to prevent fires and other disasters. The MPS-CTU-01-00 protection relay is specifically designed for medium-voltage applications, protecting the system from faults when they occur and providing a safe and reliable operation in a wide range of scenarios. This article will discuss the application field and working principle of the MPS-CTU-01-00 protection relay.

The MPS-CTU-01-00 is a three-phase overcurrent detection and protection device which has been developed for industrial applications of up to 10 kV AC or 20 kV AC. It is suitable for motor starter protection, transformer overload protection, line overcurrent protection, and other overcurrent protection applications. The device offers high sensitivity and accuracy due to the use of advanced overcurrent sensing technology. The protection range is adjustable from .125A to 10A, 20A, and 30A with a current transform ratio 1, 2, 5, 10, 15, 20, 25, and 30A. It has a range of response times from 0.1s to 1s, depending on the application, with a maximum switching capacity of 10kA. The MPS-CTU-01-00 is also temperature-compensated and can withstand temperatures up to 60°C without any damage.

The MPS-CTU-01-00 operates on the principle of differential current detection. The device is designed with two current transformers which detect the differential current between two adjacent circuits. When this differential current exceeds the preset threshold, the relay actuates and shuts down the circuit, preventing any damage that may have otherwise occurred. This feature also allows for greater accuracy in measuring the fault current, as opposed to using a single current transformer, which can be inaccurate in some cases due to the influence of environmental factors. The device also features a wide range of diagnostic capabilities, allowing users to quickly analyze the state of the system in order to take corrective action.

The MPS-CTU-01-00 is compatible with most control systems, and it can be easily integrated into existing installations. It can be used in a wide range of applications, from motor and generator protection to transformer overload protection, line fault protection, distance protection, and arc flash protection. In addition, the device has a higher anti-interference capability, which improves its accuracy and decreases probability of false trips. The product also meets multiple international safety standards, such as UL, IEC, and ITEC, ensuring that users can make full use of the device without sacrificing safety.

Overall, the MPS-CTU-01-00 protection relay is a highly reliable and accurate device that can be used in a wide range of applications. It provides a fast response time and features a wide range of diagnostic capabilities. Moreover, it meets multiple safety standards and has a high anti-interference capability, making it a great choice for medium-voltage applications.
