High Voltage DC Generator Tester
I. Introduction:
Portable DC High voltage generator is an important equipment for DC voltage withstand test and leakage current test of HV electrical equipments, cables, surge arresters in electriv industry and power supply departments.
This DC hipot tester is developed based on the calibration made by National HV Meterage Station, it accords with the standard "Generation Requirement of Portable DC HV Generator"(ZGF 24003-90)
The new technology, new material and optimal selected components are applied, It has the advantages of high power, small volume, light weight, good performance and high stability.

III.Features:
1. High reliabiliy: high frequency voltage multi-doubler reticfier, simple circuit, high overload capability, rare fault, without maintenance.
2. Small volume: one person can carry the largest DC HV generator (200kV/2mA). Its volume is only 1/(2～5) as the volume of the same kind of equipment made in Japan. It reaches the advanced level in the world.
3. Perfect seal by metal housing, high mechnical stength. Irs performence will not be influenced by viberation, moisture, dust and meterological condition.
4. Safe, convenience in operation, metal housing grounded. built-in HV terminals.
5. There is no high voltage and low voltage connecter outside, easy connection.
6. Good auto protection function.This DC Hipot kit can not be switched on if the HV output knob is not at zero position. Poeration is simplw. It will not cause maloperation and automatically switch off in over voltage and overcurrent case. There is dampong resistor indide.It is not necessary to connect damping resistor outside.
7. Excellent accuracy: The leakage current at HV side is meadured by digital meter accuracy: 1uA, range switch is not required, disvharge withstand current measurement function is available at low voltage side, It uses precise resistor with good stability to measure high voltage.
