Partial Discharge Tester DAC-PD-7





Download Catalog

DAC-PD-7 is an ideal PD tester for quantitative diagnosis at production and inspection of electrical parts, such as EV motor, Photo-coupler, IGBT, and insulation materials etc. PD tests according to the international standard (IEC 60270, 60664-1. 61730-2) are available with PC Software.



  • All-IN-ONE UNIT.
    The tester contains 3000V high voltage source, coupling capacitor, detector and calibrator.
  • EASY TO USE. No need cumbersome wirings.
  • Calibration is automatically done while voltages are being applied.
  • Automatic gain adjustment happens in designated intervals. No need to switch measurement ranges.
  • Measurement of the maximum discharge pulse Q-max is possible in each cycle.
  • Measurement can be conducted while observing discharge waveform. The applied voltage profile can be observed simultaneously.
  • RS232C interface is attached. Automatic measurement with attached software is possible.
