This test set is designed for power supply and distribution systems, power transformer manufacturers, industrial and mining enterprises, and scientific research institutions. It performs insulation strength tests under power frequency or DC high voltage for a wide range of high-voltage electrical equipment, electrical components, and insulating materials, serving as essential core equipment for high voltage testing. The system features an elegant, lightweight appearance and simplifies all test procedures.
The partial discharge detector is equipped with an LCD screen that displays the partial discharge value, withstand voltage value, and other key data. Its clean design and straightforward operation allow new operators to become proficient quickly.
The power supply of the partial discharge detector adopts a built-in isolation filtering design inside the cabinet. This eliminates power supply clutter interference while maintaining a neat appearance, with no extra wiring required for customers — realizing true plug-and-play use. A separate detailed operation manual is provided for the partial discharge detector and is not elaborated here.
