12 kV oil test cell

The CP TC12 oil test cell precisely determines the dielectric constant, the dissipation factor (tan delta) and the power factor of insulating liquids such as transformer oil. This allows signs of ageing in the oil to be documented.

Key features

  • Small case dimensions (22 x 25 cm/ 8.6 x 9.8 in) and lightweight (approx. 6 kg/13 lbs.)
  • Tests voltages up to 12 kVeff


The CP TC12 determines the following variables in insulating liquids:

  • Dielectric constant
  • Dissipation factor (tan delta)
  • Power factor
