Safety Tester
Impulse/Surge 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.

  • High-frequency harmonics analysis has the capability to detect slot lines
  • Low power non-destructive test analysis
  • Automatic Level Control Function (ALC) 
  • Waveform learning comparison to achieve rapid test speed
  • Measure voltage up to 10,000V
  • Measure the lowest inductance to 0.5uH
  • Interchangeable between Chinese and English operational interfaces/ Provide statistic and print functions
  • High-frequency noise signal analysis has the capability to detect slot line
  • Auto voltage Learn function
