heal.abstract	A new methodology combining both High Voltage Techniques and Multicriterial Decision Making is presented in this paper. This method is applied on a Power Utilities' dilemma about the selection of the optimal insulator type at the construction of a new electrical network. This selection has been done among ten different types of insulators, which are widely used by Power Utilities. Initially the criteria on which the problem is based on are determined, in order the method to be applied. These criteria are four and concern the cost, the critical flashover voltage, the creepage distance and the diameter of the insulator. Each criterion has been expressed in a common reference scale and the values of the criteria have been normalized. A different weight is given to each criterion, characterizing its importance to the decision making. Finally, a matrix, which contains the four criteria and the possible choices is used to calculate the rate of agreement and the rate of disagreement. By making the proper combinations between the values of these two rates the method infers the optimal insulator type.	en
