Product Description

AC Hi Pot Tester for Dielectric Withstand Test

Product Introduction:

Weshine® AC Hi Pot Tester for Dielectric Withstand Test, the two pieces design allows the operator to use the unit at a safe distance. The control unit is used to operate the high voltage transformer. The unit consists of a variac, current/ voltage display instruments, a timer for the test duration and a safety circuit. The low voltage winding can be continuously excited from zero to the maximum value so that a certain output is available for a pre-determined period. The operating duration depends on the application, ranging from a few minutes to continuous operation.

The input voltage of AC Hi Pot Tester for Dielectric Withstand Test series is 200V or 400V, which is connected to the matching control box (table), and the input voltage is adjusted to the primary winding (low voltage) of the test transformer through the auto voltage regulator. Using the principle of electromagnetic induction, the secondary winding (high voltage) press Its ratio to the number of turns of the primary winding can obtain the same multiple of the output high voltage, which can be continuously adjusted from zero volts to the highest rated value. In the DC withstand voltage and leakage current test, as long as the high-voltage silicon stack is screwed on the high-voltage output end, the DC high voltage can be obtained, and its amplitude is 1.4 times the power frequency high voltage value.
