Lightning Impulse withstand test is a destructive test carriedout on high voltage switchgear. It is classed as a destructive testas 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 Voltagerating 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 asecond means of isolation, ie a disconnector. This disconnector canbe a two position (mains on, off) or three position (mains on, off,or earth on) disconnector operated off load which is in series withthe Circuit breaker.
To pass the test 15 shots at +95kV and 15 shots at -95kV arefired 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 sidewill be connected to the impulse generator and the other side willbe earthed. Positive and Negative shots will be fired and theimpulse can not flash through the air gap to the earthed side ofthe disconnector.
This proves the isolation gap inside the disconnector has a BILrating of 95kV.
Therefore if the incoming side of a switchboard is live and theoutgoing side is isolated for maintenance. There can be a transientimpulse on the live side of the circuit and it will not flashacross the isolating gap and endanger anyone working on the deadside of the circuit
What is impulse current?
lighting impulse current upto 200000 amperes crest are generated by charging the set of capacitor in parallel and discharging them in same way in a test object which is usually a surge diverter or high rupturing capacity-fuse.
Define rated impulse voltage?
Simply, the voltage which is withstand by the test object as an impulse is called as rated impulse voltage.
What are the applications of high voltage?
high voltage is used for testing of motors such as lightning impulse test,surge test etc...
Why negative impulse is applied during Impulse voltage test?
The lightning phenomena is occurred on transmission lines or sub-stations due to which a negative wave is generated hence definitely destroy the power apparatus. So for impulse voltage testing of any power apparatus one must produce a negative impulse.

What is Disconnector Switch?
to disconnect the circuit when faults occurs Answer A 'disconnector switch' is another term for an 'isolating switch' or 'isolator'. It is a manually-operated switch used to provide a visible break between a de-energised part of a circuit and the energised part of a circuit so that work can be carried out safely on the de-energised part. A disconnector switch is not intended to break a load current, and most certainly not designed to break… Read More
How do you do a continuity test on a lighting circut?
A lighting circuit is a continuity test on it's own. If anywhere on the loop the lights don't go on, it's an indication of fault. then u can further scrutinise that area. If it's prior to connection of electrcity then u test from the beginning of the loop and the end of it. Put the tester across the live terminals in there.
Is impulse body spray tested on animals?
yes the company who makes impluse does test their products the company is called unilever and on the peta website has their name on thier compants that does test on animal :(
How do you make a sentence with impulse?
I bought the hat on impulse. It was just an impulse.
How do you make sentence for word impulse?
Impulse often spurs inventions. Impulse is often caused by heightened desire. Impulse often catalyzes action. An impulse should be only be acted upon as a last resort. Impulse often creates unanticipated problems. Impulse can be beneficial or dangerous. His conclusions were driven by impulse rather than logical. Impulse is often associated with heightened desire. Impulse often brings about needed actions.
What is a neuron impulse?

Impulse and momentum does impulse equal momentum or change in momentum?
What is direction of impulse?
The impulse on the colliding objects will be equal and opposite. impulse = m(vf- vi)
Why is it difficult to test complete High Voltage arresters with impulse currents?
It is because the space we have in the impulse current test system for the test object (Arrestors) is too small. So, its advisable to use a single disc, which has been taken from the slack of discs in the tube of Arrestor, and after testing of single disc, we can calculate the results for the whole arrestor. Moreover, the energy from the capacitor banks required to switch the 'Gap' (which can be triggered) is… Read More

Which internal feature prevents m-9 from firing when the slide does not return to the full battery position after a malfunction?
How do you megger test continuity on a basic lighting circuit city and guilds level 2?
You don't megger test continuity. You test for that with a continuity meter or ohmmeter. 'Meggers', as they're often called, produce high voltages to test the integrity of a conductor's insulation.
Does a moving object have impulse explain in 2 lines?
An object moving in a frictionless envirnment has not impulse, but in all other moving objects have impulse. Impulse is defined as a change in momentum and therefore if the object is slowing due to friction it is has impulse.

Difference between impulse and momentum?
Impulse is another name for change in momentum.Both momentum and impulse have same unit( Ns or kgm/s) . Impulse is also defined as force acting for a time 't'. so, Impulse=F*t
Can a moving object have impulse in itself?
No. Impulse is a change in momentum and so a moving object with a constant velocity has no impulse. in real life air resistance imparts an impulse to the object slowing it down but the object cannot really be said to have impulse
Can a moving body have impulse?
The way I understand it, a moving body has momentum, not impulse. The word impulse is used for a TRANSFER of momentum.

the Rat Impulse LTD has: a regulator, The regular Rat Impulse does not.
What is meant by impulse?
impulse is also called as sudden force or energy and called sudden shock impulse = force * displacement
