The substation is fed from 110 kV substation Pathanamthitta through one 33 kV feeder (33 kV PTPE feeder). The two 11 kV feeders RPG 1.RPG-2 are fed from the small 2x2 MW hydroelectric project at Ranni Perunad works under the tail race of 12 MW, Maniyar Hydro Electric Project by Carborundum Universal Ltd. The RPG-1 and RPG-2 are mainly used for ...

A mobile substation is a substation on wheels, containing a transformer, breakers and buswork mounted on a self-contained semi-trailer, meant to be pulled by a truck. They are designed to be compact for travel on public roads, and are used for temporary backup in times of natural disaster or war. Mobile substations are usually rated much lower ...

Distribution lines of 66kV, 33 kV, 22 kV, 11 kV, 6.6 kV and 400/230 volt electricity distribution network connect to the National Grid via transmission substations will have their voltages stepped down by transformers.
Note that the voltages are nominal and vary depending on load and distance from the substation. As of 2023 many trams and trains use on-board solid-state electronics to convert these supplies to run three-phase AC traction motors. Tram electrification systems are listed here.
Kedron Substation site is still in use as a 33 kV zone substation, but Erwoods's original building, built c. 1933 was designed to take underground 11 kV supply from the New Farm Powerhouse. Kedron Substation was also where the BCC's 33 kV transmission line to Somerset dam originated, which was constructed on-site about the same time as the ...
