The paper gives overview of methodology for calculations of reliability and outage probability of switchgears. The parameters of reliability for some types of 110kV substations` switchgears are calculated at the work. There are also compared switchgear schemes with different types of isolation – Air Insulated Switchgears (called AIS) and Gas Insulated Switchgears (called GIS). The calculations approved that two-busbar switchgear has higher reliability comparing to other schemes of switchgears. Calculations performed in the paper can help in making decision about usage of particular switchgear for each specific substation.
