Intelligent 50kVA 150kV AC Withstand Testing System for High Voltage Equipment Insulation Diagnosis Including PD Monitoring for Transformers Capacitors and Substation Apparatus

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.

• Intelligent Insulation Assessment: Combines high-voltage withstand testing with monitoring of partial discharge activity.
• Sensitive Fault Indication: Weak PD signals can provide early indications of potential insulation defects.
• Strong Anti-Interference Capability: Adaptive filtering suppresses background electromagnetic noise.
• Stable Measurement: Helps maintain reliable detection performance in complicated electrical environments.
• Comprehensive Equipment Coverage: One testing platform can serve multiple categories of high-voltage apparatus.

• High-voltage insulation diagnosis
• Transformer and instrument transformer testing
• Generator insulation evaluation
• GIS and switchgear inspection
• Capacitor and bushing testing
• Substation equipment testing
• Power equipment maintenance and commissioning
