The inflatable, no-partial discharge (PD) combination electrical tester is suitable for conducting insulation withstand voltage tests, partial discharge tests, and GIS transformer accuracy tests on high-voltage, large-capacity GIS and GIL power equipment. It is an essential device for preventive and factory testing at GS substations, GIS and GIL power equipment manufacturers, and manufacturers of pot-type insulators and insulation components. Adding a high-voltage bushing port to the device allows high voltage to be extracted, enabling various high-voltage tests on conventional high-voltage equipment.

Main Features

1. A vehicle-mounted hydraulic lift mechanism allows for easy mobility and facilitates on-site testing.

2. High voltage is fully enclosed within a shielded enclosure, ensuring safe and reliable testing.

3. The overall PD level can be controlled to within 1-3 pcs.

4. Compact size minimizes space requirements and lightweight components.

5. A built-in high-voltage disconnector enables multi-purpose use.

6. Easy connection: Direct connection to the test product facilitates testing.

7. Rugged and durable construction withstands long-distance transportation.

Technical Parameters

1. Voltage Levels: 100kV, 200kV, 250kV, 300kV, 500kV, 800kV, 1000kV

2. Capacity: 50-2000kVA

3. Input Voltage: 0.35-10kV (primary voltage)

4. Partial Discharge: 1-3pc at rated voltage (normal environment)

5. Temperature Rise: No more than 65kV (50Hz) after 60 minutes of operation at rated current

6. High Voltage Generation Method: High-voltage transformer step-up and series resonance (power frequency, variable frequency). All step-up methods are single-stage, no cascade step-up required.
