  • 5 Differences Between Air-Insulated Substations and Gas

    ConstructionInstallationOperationMaintenanceTotal Cost of OwnershipGIS high voltage substation engineering uses the gas sulfur hexafluoride for insulation, whereas AIS uses air insulation in a metal-clad system. Sulfur hexafluoride is five times heavier than air and offers excellent extinction behavior. Another significant construction-based difference between the two switchyards is that a metal-clad AIS uses three-position draw-out circuit breakers (on, off and test). GIS systems use fixed, mounted circuit breakers. The sealed mounted breakers are a ‘sealed...

A station is typically designed according to some quantifiable performance levels, as outlined in Section 3.4 of IEC 60071-2 and in IEEE 1313.2. Moreover, IEC 62305-2–2010 identifies tolerable risks for a substation, where risk level is affected by different types of service loss. Required Insulation Withstand Level (Urw) This is given in terms of surge types such as fast, very fast, slow and temporary overvoltages. Safety Margins The safety margins typically used in substations are 15% for transformer windings and 5% for air insulation. Separation Distance This is the distance between arrester and intended protected equipment. If too great, voltage at the protected equipment could exceed its required insulation level due to reflections and traveling waves. Open Bre...
