The new DC high voltage generator provides a DC high voltage source, which is specially used to test the electrical insulation strength and leakage current of power devices. The intelligent DC high voltage generator is the latest research, design, and manufacture according to the requirements of China's industry standard ZBF 24003-90 "General Technical Conditions for Portable DC High Voltage Generators". It is a product of the new era. 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, non-grounding protection, etc. 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 in about 10 microseconds, thus protecting the instrument from damage to the greatest extent.
