AC Substation: EHV, HV, MV), LV;
HVDC substation
ii) Classification-outdoor or indoor.
Outdoor substation is under open sky. Indoor substation is
inside a building.
iii) Classification based on configuration, e.g.:

b) SF6 Gas Insulated Substation (GIS)
c) Composite substations having combination of the above two.
iv) Classification based on application.
a) Distribution substation
b) Switchyard in Generating Station
c) Switching substation (without power transformers)
d) Sending-end substation
e) Receiving substation
f) Factory substation
g) Compensating substation e.g. having static var compensation etc.
h) Load substation, e.g. arc-furnace substation.
