This is the peak voltage for a 50% probability of flashover or disruptive charge.
Because you can touch the live wires and the voltage can kill you.CommentIt's quite unnecessary to 'touch' the live conductors. Approaching them within a few metres (depending on the voltage) will be sufficient for the high voltage to 'flash over', and inflict fatal burns. And if the burns don't kill you, the resulting fall will certainly finish you off!
A: TRIAC will break over and conduct at a certain if a certain voltage is reached. That voltage depends on all different triacs devices
Less likelihood of electrocotion.
forward breakover voltage is slightly smaller than reverse breakdown voltage
To answer this question the supply voltage and the amperage of the load must be given.
Impulse is the product of force and the time over which the force is applied. Therefore, impulse is directly related to force, as a larger force applied over a longer time will result in a greater impulse. Mathematically, impulse is equal to the force multiplied by the change in time.
The impulse has to cross over a synapse to another neuron or an effector.
No, impulse is the change in momentum of an object over a certain time interval. Momentum is a measure of how difficult it is to stop an object's motion, while impulse is the force applied to an object over time. So, impulse and momentum are related but not equal.
Force applied over a period of time has the dimensions of momentum, and is referred to as "impulse".
The impulse of a force is the product of the force and the time it is applied. In this case, the impulse is 10N * 5s = 50Ns.
Impulse is calculated by multiplying the force applied to an object by the time interval over which the force is applied. The equation for impulse is J = F * Δt, where J is the impulse, F is the force, and Δt is the time interval.

Lightning Impulse withstand test is a destructive test carried out on high voltage switchgear. It is classed as a destructive test as each shot damages the insulation and lays carbon tracks. The Energy Networks Association Technical Specification (ENA-TS) 41-36 states the BIL (basic Impulse level) Required for the Voltage rating of the piece of switchgear rated up to 36kV. For example an 11kV switchgear will have a BIL of 95kV. Switchgear which include a Vacuum circuit breaker must have a second means of isolation, ie a disconnector. This disconnector can be a two position (mains on, off) or three position (mains on, off, or earth on) disconnector operated off load which is in series with the Circuit breaker. To pass the test 15 shots at +95kV and 15 shots at -95kV are fired at all positions of the disconnector and only 2 out of the 15 (and not the last 5) shots can flash over to earth. For example if the disconnector was in the off position one side will be connected to the impulse generator and the other side will be earthed. Positive and Negative shots will be fired and the impulse can not flash through the air gap to the earthed side of the disconnector. This proves the isolation gap inside the disconnector has a BIL rating of 95kV. Therefore if the incoming side of a switchboard is live and the outgoing side is isolated for maintenance. There can be a transient impulse on the live side of the circuit and it will not flash across the isolating gap and endanger anyone working on the dead side of the circuit
To calculate impulse in a physics problem, you multiply the force applied to an object by the time over which the force is applied. The formula for impulse is Impulse Force x Time. Impulse is a vector quantity and is measured in Newton-seconds (Ns) or kgm/s.
