Description

Description :

To meet the development requirements of non-power interruption and Condition based maintenance, real-time monitoring of power equipment operation status under uninterrupted power supply is achieved through intelligent technologies such as the Internet of Things (IoT) and smart sensors. By utilizing intelligent sensor monitoring technologies including Transient Earth Voltage (TEV), Acoustic Emission (AE) & Ultrasonic waves, and temperature sensing, the operational status of switchgear is monitored in real time. Smart diagnostic algorithms and multi-dimensional.The system can visualize the monitoring data, allowing maintenance personnel to intuitively observe the changes in various parameters of the equipment and quickly judge the operating situation. Meanwhile, the system has a powerful self - calibration function. It automatically calibrates the sensors regularly to ensure the long - term accuracy of the monitoring data, continuously safeguarding the stable operation of the ring main unit.
