GDZG-300 series of DC high voltage is mainly used to inspect and test the performance of the insulation materials under the action of DC voltage, to conduct the insulation performance test for the large capacity test products (power cables, power capacitors and generator sets) and to measure the leak current in high-voltage electrical products made of insulation materials.
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.
Features
• Simple operation and complete function is easy for wild work. • Higher voltage stability , smaller ripple coefficient. • More reliable and more stable and can stay continuous discharge directly to earth. • High precision and exact measure and use figure display and good performance of anti-jamming. • It has high stabilization of voltage regulation and regulates voltage Smoothly.
• The over voltage set fuction uses number dial switch which can display the figures of voltage clear.
