Impulse Winding Tester

7713  is a 2-channel 10KV  impulse winding tester and able to measure inductance down to 0.5uH as well as magnify high-frequency harmonics to prevent shorts between the layers of windings. Mild corona occurring between coils would create harmonics with small amplitude and high frequency (>10MHz) which cannot be detected by a regular impulse winding tester that can only observe mild amplitude without actually identifying the fault. MICROTEST 7713 deploys “High-frequency harmonics analysis HARM “technique to magnify high-frequency harmonics then display them on screen then identify each mild discharge between layers and ensure the quality of each component coil.

  • Measure the lowest inductance to 0.5uH
  • HARM analysis and HFLT analysis
  • High voltage calibration
  • programmable impulse voltage, low-energy detection without damaging the DUT
  • Built-in storage 200 sets testing waveform
  • Storage golden sample (DUT) standard waveform in the instrument, and compare with the other sample waveform
  • Provides 5 waveform comparison: total area comparison, differential area comparison, wave comparison, futter and corona 
  • Key lock function to prevent operators from accidentally touching keys
  • Support RS-232, remote and printer interfaces
