What is a megger test?
If you are referring to a megohm meter, it is a test of the insulation properties of such things as electric wiring, motor windings and high power antenna mounts. We use a "megger" or "meg out" electrical wiring and equipment to see if it is shorted to ground in any way.The megger uses much higher voltages to check resistance than a normal Volt-ohm meter.Ideally, you want infinity resistance but I've installed 460 volt motors with 750 meg ohms resistance to ground and had no problem.On the whole megger testing is non destructive. What happens is a DC voltage is applied to the device or winding under test. It is an insulation test to see is the insulation has been injured in any way to cause a short circuit when normal power is applied to it. On my megger there are 3 ranges 300V, 750V, and 1000 volts. Applying the proper voltage is essential to not damaging the device you are testing.Working voltages up to 240 volts should use the 300 range.Working voltages up to 600 volts use the 750 volt range and working voltages above 600 use the 1000 volt range.As you can see if you used the 1000 volt range on a device that had a working voltage of say 24 volts you could damage the insulation just by testing it. So meggering a device is non destructive if you use the tester as its instructions tell you to.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
How do you megger the windings of a single phase motor?
Using a megger you check from either positive or nuetral to ground. The megger should read open (usually OL). It doesnt matter which connection you choose as long as one is ground. If the megger shows anything other than open the windings are bad.
Who ruled the world before the Volturi?

How can you measure the resistance?
It is done with an instrument called a megohm meter or megger. On the whole megger testing is non destructive. What happens is a DC voltage is applied to the device or winding under test. It is an insulation test to see is the insulation has been injured in any way to cause a short circuit when normal power is applied to it. On my megger there are 3 ranges 300V, 750V, and 1000 volts.

So meggering a device is non destructive if you use the tester as its instructions tell you to.
Can you megger test in rain?
No you cant, simply because the rain will cause a short to ground causing low insulation (megger results)... The only way is to make sure the phase you are testing is dry and no path from phase to ground is present. usually drying the phase the sanding it down while keeping it covered will give you more realistic results or you can just wait till the rain stops :)
When your measuring resistance is there enough electricity in the wire to cause you harm?
If you are using a standard ohmmeter, no, voltage is usually less than a volt. If you are using an insulation tester, or 'megger' then yes, very high voltages are used. The most common injury is caused by involuntary muscle movement though, not electrocution.
How does hail affect humans and other animals?
Hail can cause injury or damage to humans and animals when it falls from the sky during a severe storm. For humans, it can cause cuts, bruises, or concussions if they are caught outside without protection. For animals, hail can harm them if they are exposed to it, especially those kept outdoors.

What could be a cause of ergonomic injury?
One cause of an ergonomic injury could be typing at a keyboard with improper posture or positioning. The improper technique could cause carpal-tunnel, the ergonomic injury.

no
Can injury that required a plate in the head cause severe pain in the head?
Yes, any injury to the head can cause ongoing headaches.
Can a brain injury cause arthritis?
We don't know exactly what the cause of arthritisis, however it is unlikely that a brain injury would bring it on.
Can a chest injury cause a concussion?
Only if the chest injury causes you to hit your head.
