Mobile HV AC Resonant Test System with Variable Frequency is designed to generate high voltage AC power at variable frequencies to perform resonant tests on insulation systems, cables, transformers, and other electrical apparatus. It is equipped with advanced features to ensure accurate and reliable test results, including PD (partial discharge) detection and suppression technology to prevent corona discharge and ensure a clean test environment.

1. Rated input voltage: three-phase AC 380V ± 10%, 50Hz
2. Output frequency range: 30Hz~300Hz, continuously adjustable
3. Frequency instability: ≤ 0.05%
4. Voltage instability: ≤ 1.0%
5. Nonlinear distortion: ≤ 1%
6. Partial discharge capacity: ≤ 10pC

1. One vehicle independently completes the series resonance withstand voltage test.
2. The testing platform can be automatically deployed without the need for on-site lifting, and the testing equipment can be deployed smoothly with a small footprint.
3. The main circuit wires are fixed and do not require repetitive wiring work.
4. A humanized operating space, with various control switches arranged in a functional area for easy identification and operation.
5. Customizing car models according to customer needs

Mobile HV AC Resonant Test System with Variable Frequency can be used as well for other on-site testing,such as transformers,GIS,rotating machines,or high voltage cables.
The system stays within the load and size limitations for permission-free road use.Additionally,the matching transformer and the reactor are filled with ester instead mineral oil.Thus,it can be easily transported to a substation,power plant,or other high voltage areas for testing HV components after installation or repair.Additionally,it is applicable for condition assessment and fault investigations.PD measurements can be performed in non-shielded environments as part of the on-site acceptance test on a power transformer,or as a method to locate PD failures acoustically,or by electrical measurement.
It is designed for performing routine and special tests according to standards as IEC 60060-3,IEC 60076,and IEEE Standard C57.113-2010 and,thus,giving accurate and reliable test results as known from acceptance tests performed in a static test field of a factory.
