Product Description

DC high voltage HV hipot  tester  for cable, arrester test

I. Summary
Newly researched, designed, and manufactured according to "Common technical condition for portable DC HV generator" of China Industry Standard, the HMZGF series DC hipot tester is a technology product of new era, suitable for DC HV test on zincoxidearrester, magnetic blow-out arrester, power cable, generator, transformer, and switch in electric power department, scientific research unit, railway station, power plant, chemical plant, etc., a optimal upgrading product in new era.



II. Application

1) MOA lightning-arrester HVDC hi-pot
2) HVDC hi-pot and leak current measurement for HV electrical equipment, such as transformer, switchgear, and oil-type power cable
3) Leak current measurement for water-cooling DC power generators
4) High-stability DC HV generators with high-precision DC voltage-divider for DC HV standardization

III.Main Feature
1.dc high voltage generator(dc high voltage tester) is portable at site,light in weight & small size
2.With AIPWM technology, avoid the inaccuracy linearity of PWM ,High precision, exact measure,and Ripple factor ≤0.5 %
3.AI Zinc Oxide arrester and oil-immersed transformer measure function ,test report can be saved directly,accuracy ≤0.5 %, 75% UDC 1mA function button.
4.with AI technology to set over-voltage protection and over-current protection instead of digital dial switch which can only set voltage value,Error ≤1% .
5.Full range of smooth voltage regulation, voltage regulation precision ≤1%, stability ≤1%, voltage and current error ≤ 1.0%±1
6.With the total time T1 and segment timing T2, and arbitrary voltage, current timing function
7.dc high voltage generator(dc high voltage tester) adds a calendar and time function
