|MEWOI8500 DC high voltage generatorare researched and manufactured in light of China industry standard ZBF 24003-90 《Universal technology Conditions about portable DC Hipot Tester》.They are applicable to the electric power branch, power department of factories , scientific research units, railway, chemical industry, power plants, which use them to do test on zinc oxide arrester ,magnetic blowing arrester, power cables, generators, transformers, switches and other equipments.|
DC high voltage generator are used IF voltage circuit and the latest PWM technology to do closed-loop adjustment and used voltage feedback to improve voltage stability. The use of high power IGBT devices with excellent Performance and their drive technology, and the measures about special shielding, grounding and isolation in accordance with electromagnetic compatibility theory，all of this makes the DC high voltage generator high-quality, portable and can withstand the rated voltage discharge and prevent being damaged.
The major advanced technology components of HF series DC high voltage generator equipment are made from the United States, Germany, Japan and other countries so that the equipments become more reliable and more stable.
|1. It’s the smallest and lightest in the same types of products and looks more beautiful and reliable. Simple operation and complete function is easy for wild work.|
2. DC high voltage generator are used the latest PWM technology, high power IGBT devices and voltage feedback to make the voltage stability higher, and the ripple coefficient smaller.
3. The major advanced technology components of HF series DC high voltage generator equipment are made from the United States, Germany, Japan and other countries so that the equipments become more reliable and more stable and can stay continuous discharge directly to earth.
|4. The voltage meter and current meter all have high precision and exact measure and use figure display. The resolution of voltage meter is 0.1KV and current meter is 1 uA,The figure voltage meter displays is just the voltage on tested res and it needn’t additional Inductive Potentiometer(ipot).The high voltage end is used rotund shield figure meter so it can stay the shoot of discharge and has good performance of anti-jamming.|
5. It has high stabilization of voltage regulation and regulates voltage smoothly. The output voltage regulator uses a single multi-turn inductive potentiometer.
6. It has many functions such as cathode output, operating from zero, continuously adjustable, over-voltage protection, over-current protection, back to zero protection, grounding protection, special disconnection protection. All technical indexes are better than industry standards.
7. The added high-precision 75% VDC-1mA functions make it easy to do Zinc oxide Arrester tests. You just need to push it gently and the value will be displayed. There is a 75% VDC-1mA function button on the control box to do Zinc oxide arrester test. Push the 0.75 UDC - 1mA button when the current rises to 1000 uA. The value Data voltage meter and current meter shows is data of 75% .Then return the voltage ipot to zero immediately, and push the green button to cut off high-voltage power switch.
8. The over voltage set function uses number dial switch which can display the figures of voltage clear and makes it easy to operate it.The unit it displays on the dial is KV.
|9. American technology and special design is used to voltage multiplier. This makes it easy to do tests.|
10-1.Three hided supporting feet make the voltage multiplier more stable (Apply to 200KV).
10-2. The up cover of control box can be used as hurricane lamp base and cover the Voltage Multiplier to make it more stable.

characteristic of Control box
One button for high precision of 0.75UDC--1mA（precision≤1.0％）is suit to do zinc oxide lightning arrester test
overvoltage protection use dialing code set, be clear at a glance
International standard box with Two kind of using way(can be take out from the box for using) makes it easy to use.
Attention: For Combined machine design of 40KV equipment, the high voltage can be output directly with earthing cable. We can produce other type of equipments if you need.
