Space charge measurements under applied DC field by the thermal step method

This work presents an evolution of the thermal step method which allows to measure the distribution of the space charge in an insulating material whilst submitted to an external DC field. The principle and the application of the technique to flat samples are first treated. We then present the adapta...

Summary:This work presents an evolution of the thermal step method which allows to measure the distribution of the space charge in an insulating material whilst submitted to an external DC field. The principle and the application of the technique to flat samples are first treated. We then present the adaptation of this method for power cables.
