Why is there so little hazard when the 5% probability of ventricular fibrillation (the C2 line) is used as the safety limit?
The 5% probability exists if and only if the current of that magnitude flows during the T’ segment of the cardiac cycle. Many other independent factors effect the current flow, – contact resistance on the fence, earth/ground contact resistance, series resistance on the fence, current path or paths through the body, output of the energiser at that load, and the body impedance of the person in contact with the fence – when these factors are taken into account the likelihood of a hazardous event are vanishing small. The real world safety record of impulse type electric fencing shows this to be the case.
