Question
Explain with the aid of a simple diagram, the transmission of electric power from the generating station to your house.
Solution
- The 11000 volt, or 11 KV, electric power is produced at the generating station, which is situated far from the areas that would use it. This current (A.C.) measures 50 hertz.
- This alternating current voltage is increased from 11 KV to 132 KV at GRID-SUB-STATION in order to reduce energy loss in the transmission line wires.
-
Before being sent to CITY-SUBSTATION, this voltage is reduced from 132 KV to 33 KV at MAIN-SUB-STATION.
-
The voltage is further reduced from 33 KV to 220 V at the CITY SUB-STATION before it is supplied to homes.
