Product Description
50kVA/150kV Power Frequency PD-Free AC Withstand Test System
A high-voltage insulation test should not only determine whether equipment withstands the required AC voltage, but also provide insight into possible insulation deterioration. This 50kVA/150kV Power Frequency PD-Free AC Withstand Test System is designed for professional testing applications where both withstand performance and partial discharge behavior need to be evaluated.
The system can be used across a broad range of high-voltage equipment, including power transformers, instrument transformers, generators, bushings, surge arresters, GIS, capacitors and switchgear. Its intelligent detection technology is designed to identify weak discharge activity with high sensitivity. At the same time, adaptive signal filtering reduces unwanted background noise, helping engineers obtain more reliable test data and reduce the possibility of missed or incorrect judgments.

FAQ
Q1: What is the difference between AC withstand testing and PD detection?
A: AC withstand testing evaluates whether insulation can withstand a specified AC voltage, while PD detection focuses on identifying weak localized discharge that may indicate insulation defects.
Q2: Can the system be used for different voltage classes of equipment?
A: Yes. The system can be applied to suitable equipment across different voltage levels and capacities according to the required test configuration.
Q3: What makes the PD detection function sensitive?
A: The system is designed to capture weak discharge signals and process them through intelligent filtering technology.
Q4: Is the equipment suitable for factory inspection?
A: Yes. It can be used for transformer and other electrical equipment production inspection, quality control and acceptance testing.
