Features

• Automatic data acquisition of polarisation and depolarisation currents over duration up to 200'000 s with a sensitivity of 10^-12 A. The measurement of both polarisation current and depolarisation current in time domain allows the identification of Conduction phenomena (conduction current) and Polarisation phenomena (absorption current) of electrical insulation. Thus trouble/problems of any power equipment can be solved correctly.
• Monitor ionic charges or remaining charges in dielectric materials without any voltage applications.
• 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

Applications

• Non-destructive diagnosis of electrical insulation systems: all kinds of power transformers, bushings, power cables of any design, generators, motors
• Material testing
• Production control
• Documentation of insulation properties of new high voltage equipment for anticipated comparison purposes. This can be helpful for making maintenance and end of life decisions

Accessories

• External Voltage Source PDC-Phantom-1000XE for the measurement of earthed equipment.
