AC/DC High Voltage Test Transformer is a third-generation portable DC high voltage tester redesigned and manufactured according to the requirements of the Chinese industry standard ZBF24003-90 "General Technical Conditions for Portable DC Generators". It is suitable for DC high voltage testing of zinc oxide arresters, magnetic blow arresters, power cables, generators, transformers, switches, and other equipment in power departments and enterprise power departments.

　　AC/DC High Voltage Test Transformer adopts a medium-frequency voltage doubling circuit, applies the latest PWM pulse width modulation technology and high-power IGBT devices, and adopts special shielding, isolation, and grounding measures based on electromagnetic compatibility theory. This enables the DC high voltage test to achieve high quality, portability, and the ability to withstand rated voltage discharge without damage. The AC/DC High Voltage Test Transformer is a new generation product launched after fully absorbing users' valuable opinions and conducting in-depth research.

　　AC/DC High Voltage Test Transformer adopts voltage large feedback, so the output voltage stability is greatly improved, and the voltage drift is small; the high-voltage overvoltage setting uses a digital dial switch, which can display the setting voltage value intuitively and has high setting accuracy; a high-precision 0.75U function button is added, bringing great convenience to zinc oxide arrester measurement. The output voltage adjustment of the AC/DC High Voltage Test Transformer uses a single multi-turn potentiometer, with smooth boosting process, high adjustment accuracy, and simple operation; to facilitate convenient use in different workplaces, the AC/DC High Voltage Test Transformer can be placed upright on an indoor workbench. The volume and weight of the entire tester are greatly reduced, which is more conducive to on-site operations.

　　The AC/DC High Voltage Test Transformer can be optionally equipped with a ZGF-B type fully shielded high-voltage microammeter to improve the accuracy of high-voltage measurement. The meter has strong anti-interference and impact resistance, especially suitable for on-site use. It is an indispensable instrument in high-voltage testing for power frequency withstand voltage tests and DC leakage tests on various high-voltage electrical equipment, electrical components, and insulating materials. The AC/DC High Voltage Test Transformer product has the characteristics of small size, light weight, compact structure, simple use, safety, and reliability, especially suitable for on-site testing.

　　The AC/DC High Voltage Test Transformer is a new type of high-voltage testing equipment. This series of products adopts a single-frame core structure, with the primary winding and high-voltage winding coaxially wound on the core, thereby reducing leakage flux and increasing the coupling between windings. The overall structure of the AC/DC High Voltage Test Transformer product is compact, with strong versatility and easy portability. It is suitable for power, industrial, mining, scientific research, and other departments, and is an indispensable instrument in high-voltage testing for power frequency withstand voltage tests and DC leakage tests on various high-voltage electrical equipment, electrical components, and insulating materials.

　　In addition to AC power frequency withstand voltage tests, the AC/DC High Voltage Test Transformer can also be assembled into a DC high voltage test device by matching with capacitors, silicon stacks, and high-voltage DC microammeters of the same voltage level and capacity, enabling the measurement of high-voltage DC leakage current.
