Transformer management relay. It is a device used to manage and monitor power transformers to ensure their normal operation and safety.

The characteristics of this type of relay are its high accuracy, reliability, and ease of use. It has multiple functions, such as measuring and monitoring the status of transformers, controlling transformer operation, and issuing alarms in the event of faults.

As a basic unit, there are two windings per phase. Each winding ½  The winding has a rated current of 5A with a 2/3 winding. The control power supply rating of this device is 90-300 VDC and 70-265 VAC @ 48-62 Hz. It has a restrictive grounding fault function, which can detect and respond to grounding faults, thereby protecting transformers from potential electrical faults.

In addition, the device also has a front panel display screen that can display the working status and related information of the transformer through an LCD. The character height of the display screen is 40 characters, which can display various information, such as voltage, current, temperature, fault information, etc.

Comply with applicable IEEE, ANSI, and NEMA standards and can adapt to different industrial and commercial application environments. At the same time, it also has multiple options to choose from, such as basic (B), enhanced display screen, and larger LCD (E), as well as options such as enhanced display screen, larger LCD, and Ethernet (T), which can meet different user needs.

Overall, it is a powerful, high-precision, reliable, and easy-to-use transformer management relay suitable for monitoring and controlling various power transformers.
