WebThe next stage in the calculation process is to find the arc energy E arc using the formulae P = I2 x R x t watt/seconds using the calculated values for arcing current I dc arc and arc resistance R arc . The value t is the disconnection time of the circuit which is found by consulting the upstream protective device time current curve. WebThe flash bang effect is affected by distance in terms of how long the effect lasts. A direct flash bang that you're sitting on vs a flash bang from one side of long a to the other side of long a will be different. Flash bangs at a distance are virtually useless. It's just best to get a friend and practice flashes together to get a feel for them.
