  • Advantages Disadvantages of Air Insulated Substation

    Air Insulated Substation (AIS) or Outdoor Substations have all switchgear equipment, busbars and other switchyard equipment installed outside open to atmosphere. In earlier days for any voltage ratings AIS or outdoor substation is employed. Indoor Substation type is only employed in places where high pollution or saline environment exists. Indoor substations are of two types...
