Functions and Features

Protection function:

Overcurrent protection: able to detect and respond to the overcurrent condition of the transformer, cut off the power supply in time to prevent the fault from expanding.

Over-voltage protection: when the transformer voltage exceeds the set value, it automatically takes measures to protect the transformer from damage.

Under-voltage protection: when the voltage is lower than the safe range, it can also carry out effective protection.

Light gas protection (some models may have): monitor the gas dissolved in the oil inside the transformer to judge whether there is a potential fault in the transformer.

Other protection functions: such as ground fault protection, etc. The specific protection functions may vary according to the product model and configuration.

High-precision measurement: adopting advanced digital signal processing technology, it measures current, voltage and other electrical parameters with high precision to ensure the accuracy of the protection action.

Fast Response: With fast response speed, it can quickly cut off the faulty circuit when the fault occurs, reducing the outage time and the risk of equipment damage.

Flexible Configuration: Support flexible configuration and programming, users can customise their personalised protection scheme by setting the functions and adjusting the parameters through the software according to the actual needs and characteristics of the power system.

Remote monitoring and control: may have communication interface, can be connected with the monitoring system, to achieve remote monitoring and fault diagnosis, improve the power system maintenance and management efficiency.

Application and Installation

Application Scenarios: Suitable for a variety of power system application scenarios, such as power plants, chemical plants, steel mills, etc., to provide reliable protection for key equipment.
