HF series, ZGF series of DC high voltage testers are researched and manufactured in light of China
industry standard ZBF 24003-90 《Universal technology Conditions about portable DC high voltage teste-
rs》.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.
HF series, ZGF series of DC high volgate testers 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 testers high-quality, portable and can withstand the rated voltage disch-
arge and prevent being da-maged.
The major advanced technology components of HF series, ZGF series of DC high voltage testers equi-
pment are made from the United States, Germany, Japan and other countries so that the equipments beco-
me more reliable and more stable.So it makes the live operation tests easy by that the Voltage Multiplier has smaller volume and larger capacity and stronger over loading capability. We judge the quality of products and
our credit standing as the life of man and constantly improve the technological level of development to produce high quality products to meet the needs of users.
