Product Applications
Mainly applicable to power maintenance departments, industrial and mining, metallurgy, steel and other enterprise power departments for DC withstand voltage testing of high-voltage electrical equipment such as zinc oxide arresters, power cables, transformers, generators, and high-voltage switches.
It is specially used to test the electrical insulation strength and leakage current of power devices. It is newly researched, designed, and manufactured according to the requirements of the Chinese industry standard ZBF 24003-90 "General Technical Conditions for Portable DC High Voltage Generators". It is a new era product. The intelligent DC high voltage generator has multiple protection functions, such as: low-voltage overcurrent, low-voltage overvoltage, high-voltage overcurrent, high-voltage overvoltage, zero-position protection, and non-grounding protection. Fault sampling uses a dedicated sensor with nanosecond-level action time, and the optical isolation element is also nanosecond-level. The action time can completely cut off the DC main circuit within 10 microseconds, thereby maximizing the protection of the instrument from damage.
