Factors determining cost and quality of the electrical insulation in the VPI-process

The construction of the electrical insulation and the carrying out of the VPI-process are critical steps in the production of rotating high voltage machines. On the other hand, the manufacture of the insulation and the VPI-process are cost factors. It is therefore important to know the factors influencing cost and quality of the insulation in the VPI-process in order to determine the optimal production parameters and to achieve a high reliability of the resulting machine. This article gives an overview of the relevant factors and some considerations regarding costs
