PowerHV offers a wide range of AC Dielectric Test Systems power ratings from 30kV to over 2250 kVAC are available. AC test systems with transformer The AC test transformer are especially designed for testing high voltage products and components, such as cables, power transformers, gas-insulated switchgears, bushings and arresters. It is also suitable to test insulation materials. They are used to generate testing high voltage and function as part of the complete system. These systems are particularly suited for tests requiring stable voltage even if the load changes under voltage (corona, wet & pollution tests) or when the load is inductive (inductive voltage transformers) . The AC test transformer can be either in insulation cylinder type with metallic cover and base or metal tank. The insulation cylinder modular test transformers can be stacked to connect in series or parallel to get larger voltage or current to extend its application range. Insulating sheath transformers is installed in an insulating sheath and is oil-cooled. Individual transformers can be connected in parallel or series to increase the current or the voltage. The possibility of stacking several of these transformer modules allows reaching very high voltage levels by keeping reasonable floor space. | Model No. | Structure | Max voltage | | YDTW | Single unit | upto 750kV | | YDTCW | Cascaded | upto 2250kV | Metal tank transformers is situated in an enclosed and earthed metal tank.

AC test systems with Resonant Reactor ( Variable inductance ) Testing of certain apparatus requires much high voltage or current that a straight AC test system is not sufficient. Thus resonant test reactor with a variable core is needed. The main advantage of such test systems is lower input power and larger output power. The resonant test system is designed to compensate capacitance in the testing circuit precisely by tuning inductance of the test system. The natural resonance frequency of the test system matches feed-in mains, usually 50/60Hz. When the test system gets in resonance, it generates continuous testing high voltage. AC resonant test system is used for factory testing of middle, high and ultra-high voltage cables, capacitors, generators, motors, power transformers and gas-insulated switchgears. The resonant test systems can be either in insulation cylinder type or metal tank. Insulation cylinder reactors are in module and can be stacked to connect in series parallel to get much higher voltage or current. Additional voltage taps are possible for metal tank reactors. The output voltage is fed out through the tap-changers by HV bushings. This kind of reactors extend application range, and satisfy testing for cables of various voltage class. Metal tank type HV Reactor is oil-cooled which is installed in a tank made of steel. The high voltage is fed outward through the steel tank via a HV bushing. The reactor can be fitted with additional voltage taps (bushings) to achieve largest testable capacitances of test objects at lower test voltages. | Model No. | Structure | Max voltage | Max current | | XZL | Single unit | upto 400kV | 35A | Application - For routine testing of medium and high voltage cables up to 400 kV in accordance with IEC 60502 und IEC 60840
