We show the practical steps and results so you can judge suitability quickly. In this video, you'll see a complete walkthrough of how to safely perform a partial discharge free (PD-Free) AC withstand voltage test using our intelligent 50kVA/150kV testing system. Watch as we demonstrate the setup process, explain the adaptive filtering technology that suppresses electromagnetic interference, and show real-time monitoring of weak discharge signals during insulation evaluation of transformers, generators, and other high-voltage equipment.
