  • Specification

ZGF-S DC high voltage generator is designed for leakage current and DC voltage withstand test of water cooled generators. It can avoid the influence of stray current and polarization potential by compensating loop of interference currents, thus testing the leakage current of test objects. It’s especially suitable for the diagnosis of insulation integrity of stator windings of generators.
 
  • DC voltage withstand test and leakage current detection
  • Insulation diagnosis of stator windings of generators 
 
  • Interference current compensation excludes influence of stray current and polarization potential
  • Use middle frequency voltage double loop and PWM
  • Large output power and rated power due to special design
  • less weight and small size for single piece
  • Made by imported high quality devices 
  • Dot matrix LCD large screen display with timer
  • Aseismatic aluminum box ,easy to move
