• Automatic data acquisition of polarisation and depolarisation currents over duration up to 200'000 s with a sensitivity of 10-12 A (however, a typical measurement takes between 2'000 and 10'000 s)

  • Adjustable voltage source up to 2'000 volts

  • Measured time domain data can be converted into frequency domain data resulting in a continuous dielectric spectroscopy (capacitance and dissipation/loss factor) from 1 Hz down to less than 0.0001 Hz

  • Evaluation of diverse kinds of "polarisation indexes", "return voltages" and "polarisation spectra"

  • Evaluation of the ageing state and of the moisture content of especially oil-paper insulation systems

  • Ongoing measurements can be viewed real-time on large color screen
