Product Principle
It is a single-phase transformer with connection group label II. The working process of a single test transformer: AC 220V voltage (380V for above 10KVA) is connected to the power control box (console), and the voltage is adjusted to 0~200V (0~400V for above 10KVA) by the auto-transformer inside the power control box (console) (external for above 50KVA) to the primary winding of the test transformer. According to the principle of electromagnetic induction, the required high voltage for testing can be obtained from the high-voltage winding of the test transformer.
