Product Description
50kVA/150kV Power Frequency PD-Free AC Withstand Test System
For high-voltage equipment, early insulation problems can be difficult to recognize because partial discharge may occur long before a complete insulation breakdown. The 50kVA/150kV Power Frequency PD-Free AC Withstand Test System provides a testing platform for applying power-frequency AC voltage while monitoring weak discharge activity during insulation evaluation.
The system is designed for a wide range of equipment such as transformers, instrument transformers, generators, surge arresters, bushings, GIS, capacitors and switchgear. High-sensitivity signal acquisition supports detection of subtle PD activity, while the built-in adaptive filtering technology helps distinguish useful discharge signals from background electromagnetic noise. This makes the system suitable for high-voltage testing environments where stable data and accurate insulation assessment are important.
