I.Introduction
The test transformer calls the booster, it is the basic test equipment used by the power station, supplying and distributing the electrical power system and the scientific research unit. Which used in the insulated intension test on all kinds of electrical products, electrical equipments and insulated materials, testing the insulated level of products, discovering the insulated objection of quizzee, scaling the capacity burdened voltage.
They make up of the high quality cold rolling silicon steel piece by HZJ alternating current test transformer, HZJZ alternating and direct current amphibious light high voltage test transformer. The winding is the concentric pagoda and multilayer cylindrical type, low-voltage winding in inner, high-voltage winding in outside; Outer cover is portable which has characteristics, such as volume smallness, weight light, the shape prettiness and move convenience and so on.
