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!

    Assuming light bulbs come on at normal brightness, then voltage drop in the long cable is not part of it.

    Now then, there are 365 * 24 = 8760 hours in a year


    6000KHh annually  is equivalent to a steady load of 680 watts.

    Think ten or eleven 60watt light bulbs on 24/7 (or twice that load half the time or any other equivalent)


    What kind of site is this - domestic, industrial unit, farm shop ?


    I'd be looking for a heater left on, lights or refrigeration equipment running non stop, or a rack of IT equipment,


    How hot does this transformer run ?


    With a friend looking at the meter and 2 mobile phones or walkie talkies, disconnect things and verify the meter comes to a stop.
