D1 Unit 4 Essay
Task 4 (D1)
Qu6. Analyse the need for selecting the different voltages used for different parts of the generation, transmission and distribution systems drawn for Qu.5.
Back in the 1800’s Thomas Edison had a vision to power the whole of New York using DC (direct current) that he developed, this idea was brilliant, but had one set back. A power station was needed every mile due to D.C. only flowing in one direction. This wasn’t a very practical form of electricity or cost effective, another idea or form of electricity was needed. Welcome Nikolas Tesla, he came up with the idea of AC (Alternating Current) with this form of electricity the flow of electric charge changes direction periodically in relation to a sine wave. With this new type of electricity it could be sent much further due to …show more content…
Find below the configuration of a Delta-Delta transformer and the transformer setup of a substation found locally around Britain.
As electricity is essential to life as we know it, failure protection needs to be considered, these measures are normally taken when supply exceeds demand these are; brownouts- Where the generated supply on energy has dropped below the demand needed, this would be seen as lights dimming but not fully turning off. Blackouts – These occur when the supply fails altogether, these can be characterised by no electrical energy being present. Rolling Blackouts – these are created by engineers intentionally to distribute insufficient power again when demand exceeds the
