Insulation Co-ordination Studies

Insulation Co-ordination studies relate to a series of steps to determine the dielectric strength of various equipment and components in an electric power system in order to avoid failure of their insulation due to transient over voltages occurring both external and internal to the power system. Generally, these over voltages are termed as electromagnetic transients (EMT) characterized by frequencies of the order of KHz (switching transients) and even MHz in case of lightning transients. Expert team of SPC can perform detailed power system simulations to determine the maximum overvoltage stresses for existing substations, Transmission & distribution lines, industrial power systems and solar farms and also for green field projects. SPC deploys the well-known industry grade Electromagnetic Transients (EMT) simulation program for Insulation co-ordination studies. Insulation Co-ordination studies are performed to:

• design proper insulation and surge arrester locations

• determine cause of failure of equipment - root cause analysis

• validate a design of chosen insulation levels

• provide assurance that equipment is protected properly etc.
