The new DC high voltage generator provides a DC high voltage source, specifically 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 the Chinese 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, 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.
