Soken DAC-PG-103S - Winding Tester

Winding Tester


Category : Impulse testing instrument

by quote only Add to Cart



Further downsized and weight-reduced with the incorporation of semiconductors. Compatible with impulse testing for medium- to high-voltage rotary machinery windings.


  • The tester generates a surge pulse for testing Medium High Voltage Rotator Windings.
  • With an external storage oscilloscope, excellent viewability of waveforms can be obtained.
  • Eliminates unwanted stresses on specimens by minimizing the frequency of occurrence of impulses
  • Compact, lightweight design and reduced power consumption with adoption of semiconductors in the pulse generating circuits and reduction in frequency of occurrence of impulses to a required minimum
  • Developed for windings in medium- to high-voltage rotary machinery, allowing generation of impulses with a sufficient level energy also for windings of low inductances
  • Minimizes variations in waveforms in the rising phase of impulses
  • Drastically suppressed jitter compared to conventional spark-gap or gas-filled discharge tubes, and more stabilized operation attained independently of environmental conditions or mechanical vibrations owing to the adoption of thyristor switches
  • Virtually maintenance-free operation
