Ⅰ. Working principle
The input voltage of this series of products is 200V or 400V, which is connected to the matching control box (platform). The input voltage is adjusted by an autotransformer to the primary winding (low voltage) of the test transformer. Using the principle of electromagnetic induction, the secondary winding (high voltage) can obtain an output high voltage of the same multiple according to its ratio to the number of turns of the primary winding. It can be continuously adjusted from zero volts to the rated maximum value. When conducting DC withstand voltage and leakage current tests, simply rotate the high-voltage silicon stack onto the high-voltage output terminal to obtain DC high voltage, which is 1.414 times the amplitude of the power frequency high voltage value.
