INVESTMENT SAVING ACHIEVED BY IMPLEMENTATION OF INSULATION COORDINATION

A part of the equipment's costs of the high voltage networks belongs to their insulation With increasing the insulation level, the dimension and the weight of the equipment will also increase Since most of the apparatus in this voltage level are purchased from foreign countries, reduction in the insulation level causes saving in the foreign currencies. Therefore the aim of the insulation coordination is an economical design of the insulation of the electrical networks The procedure, on the otherhand, should not create any restrictions to the design engineers for the special technical cases In this article, some examples of the economical gains achieved by implementation of the insulation coordination are described
