800M 32mm SWA - could this cause increased electricity bills due to voltage loss

Former Community Member

Hi all,


Our electricity usage is very high (6,000 KWH annually) but we dont have any electricity heating or anything that should be chewing up that much electricity.


I'm looking for reasons why the usage is so high.


Our meter is actually sited on a neighbouring property and then a 35mm2 2 core SWA cable runs approx 800 meters to an Ashley Eddison transformer that regulates the voltage and amperage.


Could the length of the cable, the associated voltage drop and then the transformer usage contribute significantly to the electricity usage..?


Thanks and my apologies for any inaccuracies and ignorance!

    Yes, two very good points in the  post preceding mine. How hot does the transformer get ? Heat represents wasted energy, unless it contributes to heating the premises. (and even then it is a total waste in warm weather and a partial waste even in winter if it displaces cheaper heat sources)

    And yes, turn off everything and observe the meter, as described.


    The calculated average load of 680 watts Might consist of say 180 watts lost in the cable (much more under heavy load) and 300 watts lost in the transformer, with only 200 watts on average being applied to any useful purpose.
