  • Advantages Disadvantages of Air Insulated Substation

    2015-3-24Air 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...

  • Gas Insulated Substations | Advantages Disadvantages

    2017-11-4Gas Insulated Substations (GIS) differ from Air Insulated Substations (substations we usually see) such that all the substation equipment such as busbars, circuit breakers, current transformer, potential transformers and other substation equipment are placed inside SF 6 modules filled with SF 6 gas. The SF 6 gas which has high dielectric property acts as an insulating medium to the High
