    • variability of settings – can be used for research purposes;
    • light weight, compact size, easy to use.

The unit is designed for determining the dielectric loss tangent, specific resistivity, and permittivity of transformer oils and other dielectric fluids according to IEC 60247-2004-02 (VDE-0380-2:2005_01), ASTM D924-08, and ASTM D1169-02.

It is a fully automatic device that allows testing according to the procedures defined in these standards, as well as according to the user procedures specified in the appropriate section of the setup menu.

Operating principle

The principle of operation is based on measuring the difference in amplitudes and phases of signals obtained when a test sinusoidal voltage with an effective value of up to 2 kV is applied simultaneously to the reference capacitor and the object of measurement, which is the measuring cell of the unit.

The difference between the amplitudes of the signals taken from the reference capacitor and the internal electrode of the measuring cell is proportional to the dielectric constant of the liquid under study. The phase difference between the signals taken from the reference capacitor and the internal electrode of the measuring cell characterizes the value of the dielectric loss tangent.
