Features and Advantages
1.Configure different sensors to realize partial discharge detection of almost all electrical equipment;
2.The user-friendly human-computer interface facilitates data management for different devices, including tracking historical data trends, horizontal and vertical data analysis, and enables 360 ° comprehensive diagnosis of the device under test;
3.Built-in ultrasonic sensors and transient ground voltage (TEV) sensors can be externally connected to special sensors such as transformers, GIS, overhead lines, and cables;
4.The non-invasive detection method is adopted, which eliminates the need for power failure and additional high-voltage sources during the testing process, making it more convenient to use than traditional pulsed partial discharge detectors;
5.The test bandwidth ranges from 30 kHz to 2.0 GHz, suitable for various frequency band detection principles;
