NANAO ELECTRIC Manufacture NAZV DC High Voltage Test Set For Water Cooled Generator

Product introduction

NAZV DC high voltage test set is the equipment of testing DC voltage and DC leakage current of water-cooled generator in the situation of water through,which completely overcome the problems of long blow water time,bottom water hard to dry, easy to cause arcing within the coil. It is specially designed various kinds of interference current compensation loop, completely eliminate the influence of stray current and the polarization potential interference of the water collecting pipe during the test, and can accurately measure the leakage current of the water-cooled generator winding.

Characteristics of the products

1.Adopt medium frequency double circuit, the first application of the latest technology of PWM ( pulse width modulation ) and high-power IGBT device, and according to the theory of electromagnetic compatibility, the use of special shielding, isolation and grounding to achieve a high-quality, portable and can withstand rated voltage discharge without damage.

2.In order to accurately measure the leakage current of tested object, this instrument is specially designed various kinds of interference current compensation circuit, completely eliminate the influence of stray current and the polarization potential interference of catchment tube.

3.Electronic control and tune, easy to operate.

4.The date of voltage and current are recorded in the panel, reading without conversion.

5.One minute timing and tip function.

6.Perfect over voltage and over current protection function inside, also zinc oxide over voltage protection outside,which ensure safety of generator.

7.Both control unit and double packed with special shockproof aluminum alloy cabinet, easy to move.

8.Portable design,suitable for on-site testing.
