11kV Overheads and Water Spray.

Zoomup

You a are farmer. You have potato fields that need watering due to the lack of rain and the hot weather. You tow your water sprayer trailer out to the potato field and connect up the pipes. The water can be mains or deep bore hole sourced. The spray is very high pressure and reaches a great height. In fact it reached the 11kV overhead cables that run across your field.

Is there any danger?

Here is a static system, but yours is mobile on a tyred trailer. It does though show the height of the sprays.

    This is an impressive example. About 30 seconds in cooling towers are dropped at Didcot, Some debris flies off at the time, and then at 2mins  10 or so, the dust cloud gets to the 33kV lines, and it sizzles for the full 5 seconds before the earth fault relay does it's thing.

    ADS  is not the same protection level at HV as at 230V. Long disconnection time translates into a lot of damage.
