AC voltage withstand test transformer

1、 Function Description

AC voltage withstand test transformerIt is a strict, effective, and direct method for assessing the insulation strength of power equipment. It can detect concentrated defects with high risks and plays a decisive role in determining whether power equipment can continue to operate. It is an important means to ensure the insulation level of equipment and avoid insulation accidents. Used for conducting insulation strength tests on various electrical products, electrical components, insulation materials, etc. at specified voltages to assess the insulation level of the products, discover insulation defects in the tested products, and measure the ability to withstand overvoltage. Widely used in electrical manufacturing departments, power operation departments, research institutions, and higher education institutions.
