  The Electrical System
   
  The following drawing shows the main networks but excludes details of bus bar sectioning and couplers. Feeder detail is not shown but the 33 kv bus bar supported the areas distant from the power station - Torquay and the Teignbridge area. The 11 kv feeders fed, in the main, the local Newton Abbot area in my time.
   
  It will be apparent from the drawing that the station went through at least four stages starting with the 500 volt Direct Current (DC) switchboard, then the 11kv (AC) cellular switch board associated with generators 3 and 4 during the late 1920's. This cellular switchboard will have included generator 5 at the time of its original installation.
   
  The next station extension, in a new switch room, was the 11kv metal clad gear supporting the introduction of generator 6. Generator 5 was reconnected to this switchgear as the interconnecting reactors were introduced. At this stage all station auxiliaries were either steam or DC driven. This phase occurred during the early 1930's and was associated with the MP Station.
   
  Until 1934 the station operated as an electrical 'island' - that is supplies could not be connected from elsewhere. In 1934 the first Grid connection was made to the 11kv switchboard. - click here for a diagram of the 1934 interconnected Grid System.
   
   
  The introduction of generators 7 and 8 during the war years required the addition of station transformers to power the AC auxiliaries now used throughout the HP section of the station and the new cooling tower required to supplement the river water cooling supplies. At this time the 33kv substation was built adjacent to the Grid connection at Forde Road and this remains the main Bulk Supply point into the Teignbridge area.
