TOR-3 Oil tan delta tester

TOR-3 is designed for determining dielectric loss tangent and permittivity of transformer oils and other dielectric fluids according to the IEC 60247.

Manufacturer: GlobeCore.

Description

TOR-3 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.

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.
Features
