| 875018 | 2010-04-18 00:05:00 | Yeah, right. My brother took up mobile yodelling and cross-country break dancing simultaneously with finding that the stream did not break up anywhere near enough. Even as a five year old he was surprisingly nimble. Not only that, he beat mythbusters to the test by over 60 years. Maybe they don't make streams like they used to? Or electric fence units are getting weaker, it was a brand new Wolsley mechanical-break unit with a habit of zapping more people than livestock. Ha Ha cant stop laughing at R2s reply, my kids think I have gone nuts. We had a Wolsley shearing plant on the farm was Granddads so must have been pretty old. I guess it was same firm as electric fence makers but probably not the car manufacturer. Lol if it was the electric fence unit could have had Lucas parts in it. What does mechanical break mean? |

As the magnetic field collapsed it generated a high voltage in a secondary winding which flowed out and went to earth via cows noses or (once) through a small boy's nether regions, contact is then broken as the small boy arcs skywards. The spring attached to the flywheel (or balance wheel in clock terms) then restores the wheel to the home position. This makes the connection to the primary of the coil and the cycle repeats except that the bounce of the sprung contact assists the coil and the flywheel now does almost a full turn. This makes a fairly solid sounding clunk each pulse, and when they don't hear that the cows learn the fence is safe so it is time for fresh grass under the wire. Never managed to persuade my brother to repeat his fence tests though, so we had to touch the wire with a few inches of grass to see if the zap was present. E & OE, I was only about 7 years old when I diagnosed the machine, so things may be a bit awry. |
