Product Applications
Mainly applicable to power maintenance departments, power departments of industrial, mining, metallurgical, steel and other enterprises 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 detect the electrical insulation strength and leakage current of power devices. It is newly researched, designed, and manufactured according to the requirements of 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 dedicated sensors with nanosecond-level action time, and the optical isolation components are 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.
