Products Description
The HMYDQW-50kVA/200kVA Partial Discharge-Free Power Frequency Withstand Voltage Test Set is suitable for testing equipment of medium voltage levels and capacities. While performing power frequency withstand voltage tests, it can accurately measure the partial discharge level of the test specimen, which is crucial for assessing the insulation condition of the equipment and detecting potential defects.
Application Test Subjects
- 10–220 kV power transformers and dry-type transformers;
- CTs/PTs (current and voltage transformers), bushings, and surge arresters;
- High-voltage switchgear, ring main units, cable accessories, and insulators;
- Insulation materials, epoxy resins, and insulation testing of high-voltage components;
- Manufacturer's factory partial discharge and withstand voltage tests, third-party high-voltage laboratory testing, and power grid maintenance testing.
Product Parameters
- Rated Capacity: 50 kVA – 200 kVA (customizable)
- Input Voltage: AC 220 V or AC 380 V
- Output Voltage: Up to 400 kV or higher (customizable upon request)
- Partial Discharge Level: ≤5 pC at rated voltage
