HMZGF-120kV/3mA High-voltage generator

Profile

DC high-voltage generator, also known as high-voltage generator, intermediate frequency DC high-voltage generator, high-voltage DC generator, DC generator, portable DC high-voltage generator, high-frequency DC high-voltage generator, and AC DC high-voltage generator.
Mainly used to study the insulation strength of DC transmission and converter station equipment and insulation materials under high DC voltage, corona and ion currents in DC transmission lines and their effects, as well as to conduct leakage current tests on AC and DC power equipment. Some AC equipment with large capacitance, such as power cables, capacitors, etc., often use DC high-voltage generators for insulation tests to reduce the requirements for the capacity of the testing equipment. The DC high-voltage generator can also be used as a power source for other high-voltage testing equipment, such as impulse voltage generator, impulse current generator, oscillation circuit (see oscillation circuit test station), etc. It is also widely used in other technological fields.
