Product Description

AC Withstand Test System

The 15kVA/150kV AC Withstand Test System provides a power-frequency high-voltage source for verifying the electrical strength of insulation assemblies. Its 150kV AC test level is intended for inspection procedures where medium- and high-voltage apparatus must be evaluated under a prescribed withstand voltage before acceptance or operation.

The complete configuration incorporates an Intelligent Electric Operation Console and an Oil Immersed Test Transformer. The motorized console manages the voltage adjustment process and can provide digital operating information, while the oil immersed transformer performs the high-voltage conversion. Additional measurement, protection, and recording functions can be selected according to the customer's testing requirements.

Product Parameters

Product Advantages

• 150kV AC Test Level — Provides a high-voltage source for applicable electrical insulation tests.
• 15kVA Rated Capacity — Configured for test objects with compatible electrical load characteristics.
• Intelligent Electric Regulation — Motorized voltage adjustment makes the testing process easier to operate.
• Oil Immersed Transformer — Provides the insulation and cooling medium required for high-voltage conversion.
• Integrated Safety Protection — Protection functions can include over-voltage, over-current, flashover, emergency stop, and safety interlock.
• Digital Test Management — Optional data storage and USB export support test documentation.

Application Scenarios

1. Power transformer external insulation testing
2. Distribution transformer inspection
3. Medium-voltage switchgear testing
4. CT and PT dielectric testing
5. Insulator and bushing withstand tests
6. Motor and generator winding insulation testing
7. Short cable and cable accessory testing

Application Note: The system is primarily intended for relatively low-capacitance loads. For long cables, large GIS, or other high-capacitance equipment, a variable-frequency AC series resonant test system is generally more appropriate.
