What happened there? :angel:
There doesn't appear to have been much further news after the incident, perhaps because of the possible big bucks involved and concerns about liability. From what was reported it sounded like the insulation had broken on a disused underground mains cable that hadn't been isolated, and current to earth created a large enough potential difference at ground level to kill the two horses. All the stuff in the reports about the other horses being saved because they were wearing aluminium shoes couldn't have been right though - the danger zone was probably very localised and they missed it, or got away sufficiently quickly.
Evidently the fault current was insufficient to blow a fuse or trip a circuit breaker, which is strange considering that the cable should have been armoured and the metal armour strands connected to earth at both ends and, probably, to neutral at the supply end. But then again, the cable shouldn't have been live in the first place so it might not have been intentionally connected via a protection device.
