Three-phase high current generator   Three-phase current booster Three-phase current booster is suitable for use in different testing fields and environments such as power plants, chemical, metallurgy, coal and other industries, laboratories, and on-site workshops, meeting the diverse needs of users. In design, control technology has been adopted, making the instrument simple and convenient to operate. Users only need to connect the test cable to directly carry out calibration work, without the need for additional voltage and current regulators, monitoring ammeters and voltmeters, current and voltage transformers, and complex wiring.
