Gas insulated substation (GIS) versus Air insulated ...· 2. Maintenance. The failure rate of circuit breaker and disconnecting switch in GIS is one-fourth of that of AIS and one tenth in case of busbar, thus the maintenance cost of GIS is less than that of AIS over the lifetime. 3. Operation cost. The maintenance cost of GIS and AIS shall be equivalent.The cost for training in GIS is higher than in AIS.
