EARTH ELECTRODE A NOVEL METHOD

John Peckham
I am currently teaching a group of electricians from a company who are all South Africans or Zimbos to update to the 18th Edition.


We were working through the different types of earthing systems and I asked what did the use back home. The answer came TT. I asked what was the soil like and how deep and how many rods did they use. I will not try to mimic the accent or their terminology but words to the effect of, " We dig a big hole with a digger, lug a conductors on to a car or lorry engine and drop it in the hole with the digger and back fill".



Now I thought that was a brilliant idea given the surface area of a car engine dropped in to a deep hole. That would be ideal for an earth for my amateur radio transmitter assuming SWMBO would not object to a large hole in the front garden.

    Back during the foot and mouth disease cattle cull tractors were buried along with carcasses, however some tractors had to be dug up because the diesel,  oil and water had not been drained from them. After they were drained the tractors were buried again 


    Apart from the obvious silliness of this it's rather worrying as if the fluids from the tractors could end up  in water courses,  so could the fluids from the carcasses. 


    One of my neighbours bought a new Ford Galaxy and it was scrapped after less than six months, because he drove into flood water alongside a BSE and Foot and Mouth disease cull burial site not realising it was deeper than he thought resulting in it cutting out resulting in the car having to be recovered. 


    Perhaps burying engines or complete vehicles is not such a good idea ?
