AC test systems consist of modular transformer units that can be cascaded up to three stages to get higher voltages ranging up to 1200 kV. Our AC test systems can be provided with low or high power ratings. Small AC test systems with low power are mainly suitable for performing dielectric tests, whereas large systems with high power can be used to carry out additional tests such as high voltage withstand tests.
