Hatch Posted 12 February, 2011 Posted 12 February, 2011 Just seen this, this is very strange. Something very, very odd has occurred here.
gaz Posted 12 February, 2011 Posted 12 February, 2011 Very strange. Moles or Rabbits chewing underground cables, so wet grass and metal horseshoes all combined? Apparently Channel 4 showed footage of it. Someone took a screencap and put it on Youtube but its been removed.

Special K Posted 14 February, 2011 Posted 14 February, 2011 heard it was faulty manes I hope the other horses are in a stable condition.
bridge too far Posted 14 February, 2011 Author Posted 14 February, 2011 Is this why some horses are called chargers?
Quickfire Double Posted 14 February, 2011 Posted 14 February, 2011 What an unfortunate bit of current affairs this is.
bridge too far Posted 14 February, 2011 Author Posted 14 February, 2011 What an unfortunate bit of current affairs this is. Shocking! My first reaction was 'OHM y god'
Quickfire Double Posted 14 February, 2011 Posted 14 February, 2011 Shocking! My first reaction was 'OHM y god' I don't see watt all the fuss is about!
skintsaint Posted 15 February, 2011 Posted 15 February, 2011 I hope out of their findings they take the positives and not the negatives.
Quickfire Double Posted 15 February, 2011 Posted 15 February, 2011 Wire people not taking this seriously? It's not for meter say...
bridge too far Posted 15 February, 2011 Author Posted 15 February, 2011 I reFUSE to contribute to this thread any more.
Quickfire Double Posted 15 February, 2011 Posted 15 February, 2011 I reFUSE to contribute to this thread any more. Fair enough: you're clearly a bright spark, and know when a thread has run its course!
hutch Posted 15 February, 2011 Posted 15 February, 2011 They cancelled the meeting after it happened. Clearly a case of shutting the stable door after the horse had volted.
EastleighSoulBoy Posted 15 February, 2011 Posted 15 February, 2011 They cancelled the meeting after it happened. Clearly a case of shutting the stable door after the horse had volted. One of the better ones, remember folks that electricity Hertz.
bridge too far Posted 15 February, 2011 Author Posted 15 February, 2011 I suppose we should be grateful that the race was at Newbury and not at......... AMPfield.
Quickfire Double Posted 15 February, 2011 Posted 15 February, 2011 I thought you were done with this thread BTF - how were you caJOULEd into posting again?!
bridge too far Posted 15 February, 2011 Author Posted 15 February, 2011 I thought you were done with this thread BTF - how were you caJOULEd into posting again?! Very good I must admit I'm ALTERNATING between playing and not playing.
Pancake Posted 15 February, 2011 Posted 15 February, 2011 Really? We are making jokes surrounding the death of 2 horses?
Deppo Posted 15 February, 2011 Posted 15 February, 2011 Is this why some horses are called chargers? Not that sad, then? Perhaps we should change the thread title to How bizarre (and funny)?
hamster Posted 15 February, 2011 Posted 15 February, 2011 I reFUSE to contribute to this thread any more. If Ohmly you meant that...
hamster Posted 15 February, 2011 Posted 15 February, 2011 Really? We are making jokes surrounding the death of 2 horses? aw come on Pancake it's just a bit of polarity hilarity.
bridge too far Posted 15 February, 2011 Author Posted 15 February, 2011 Not that sad, then? Perhaps we should change the thread title to How bizarre (and funny)? I didn't start the play on words.
Quickfire Double Posted 16 February, 2011 Posted 16 February, 2011 I feel a bit sad now, if that helps preserve the current thread title at all... :sadface
Dog Posted 17 February, 2011 Posted 17 February, 2011 The root of the problem appears to have been an underground electric cable with faulty or damaged insulation, which allowed electricity to leak into the ground. The effect of this would have been to raise the voltage of the ground around the fault. The voltage rise would have been highest near the fault, falling away at distances further from the fault. This means that the voltage difference between a location close to the fault and one, say, twelve inches further away would have been small, but the voltage difference between a location close to the fault and one four or five feet away would have been much larger. This is the key to the mystery, as it’s not voltage that causes electrocution, but current. And it’s voltage difference that makes current to flow. Because people stand with their feet close together, the voltage difference between the feet of someone standing close to the fault would have been quite small, and only a small current would have flowed through their body. They would probably have felt a small electric shock, but have experienced no harmful after effects. This is exactly what the trainers reported. The situation for horses is very different, as there is a considerable distance between their front and rear feet. This means that for a horse standing in the vicinity of the fault there would have been a big voltage difference between its front and rear feet. This would have allowed a large current to flow, with the fatal results that were seen. Other factors would also have been involved. Horses have metal shoes that make good electrical contact with the ground, making it easy for current to flow, whereas people normally wear shoes or boots with soles that are electrical insulators and impede the flow of current. In addition, sudden collapse from electric shock is typically the result of heart failure caused by current passing through or near the heart muscle. An electric current flowing from leg to leg in a person, however, doesn’t go anywhere near the heart, whereas a current flowing from the front to the rear legs of a horse most certainly does. This explanation doesn’t make Saturday’s events at Newbury any less tragic, but it does offer a solution to the apparent mystery of why the horses and were affected when people in the same area were not. It also highlights the importance of regularly testing the protection systems that might have been expected to automatically disconnect the electricity supply to a faulty cable before the fault was able to cause injury and death.

It also highlights the importance of regularly testing the protection systems that might have been expected to automatically disconnect the electricity supply to a faulty cable before the fault was able to cause injury and death. It was never a mystery, it was pretty obvious. Its known as step potential and Humans would never have been in any danger (in this situation). It was an LV cable as well, so a maximum voltage of 415v would have been at the area of the fault, not the massive voltage thats been reported. Edited 19 February, 2011 by Smirking_Saint
thesaint sfc Posted 19 February, 2011 Posted 19 February, 2011 Really? We are making jokes surrounding the death of 2 horses? Neighhhhh' we're not.
Deppo Posted 19 February, 2011 Posted 19 February, 2011 I didn't start the play on words. Have some convinction. Don't hide behind faux sympathy. You clearly find it funny, so have some conviction and change the title and stop making childish excuses ("I didn't start it!")

Quickfire Double Posted 19 February, 2011 Posted 19 February, 2011 My but there's a charged atmosphere about this thread now!! Think I'll trot off elsewhere before the sparks start to fly!!
