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. -

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. |
