Test transformer, also known as booster, is a device used for testing the electrical strength of power generation and supply equipment, various electrical products, and insulation tool materials.

The dry-type test transformer series produced by our company has changed the outdated situation of old-fashioned test transformers being bulky, large, and heavy. It can also provide DC high-voltage test power after being installed with the high-voltage silicon stack produced by our company. It is equipped with control boxes (platforms), automatic protection microamperes, ball gaps, and other ancillary equipment, making it particularly suitable for on-site testing, making heavy work convenient, fast, easy, and flexible, and greatly improving efficiency. Therefore, it is highly welcomed by high-voltage testing personnel in power systems and large factories and mines.
