High Voltage Partial Discharge Testing System 150kV 20kVA for Transformer Insulation Testing and Electrical Equipment Quality Inspection
Product Description
The Digital Partial Discharge (PD) Testing System is designed for detecting and measuring partial discharge in high-voltage electrical equipment and insulation systems. With a rated output voltage of 150kV and a rated capacity of 20kVA, it integrates digital PD measurement, variable-frequency high-voltage testing, signal filtering, and intelligent control in one coordinated system.
Featuring a detection sensitivity of 0.01pC, a measurement range of 0.1pC to 10,000nC, and a low partial discharge level of ≤2pC at rated voltage under no-load conditions, the system supports insulation assessment, PD pattern observation, test data storage, and automatic report generation.
Advantage
- Integrated Testing Solution
Combines high-voltage AC test equipment, digital PD measurement, signal filtering, and control software to support coordinated insulation testing. - Sensitive PD Measurement
