Insulation Co-ordination Studies

Insulation Coordination is the process of determining the proper insulation levels of various components in a power system as well as their arrangements. It is the selection of an insulation structure that will withstand voltage stresses to which the system or equipment will be subjected to, together with the proper surge arrester. The process is determined from the known characteristics of voltage surges and the   characteristics of surge arresters.

        The following standards are used by consultants, while performing the insulation coordination:

• Insulation Co-ordination, Part 1: Definitions, principles and rules IEC 71-1, standard.
• Insulation Co-ordination, Part 2: Application guide IEC 71-2, standard.
• IEEE Guide for the Application of Insulation Coordination. IEEE Std 1313-2-1999
