The typical test equipment for this is a megger. The megger is connected to two conductors at a time to test the insulation between the two.
Insulation resistance test: This test is used to find the insulation resistance of motor for 1 min or 10 min through high voltage insulation tester. By this we can find the insulation level. Polarization index: This is the ratio between insulation resistance for 10 min to insulation resistance for 1 min.
insulation resistance can be measured by means of megger, with built in d.c generator. It is measured between the conductor and the earth. earth resistance can be measured by means of earth resistance tester. For good effective earthing, th earth resistance should be of order 0.5 ohm
No. Conductor resistance is. Cable insulation resistance to ground is inversely proportional to its length. The longer the cable, the more leakage path to ground; therefore, the lower the insulation resistance to ground.
Use a megger or a insulation tester. Place one lead on any of the phases nd other lead the alternator boy. Observe the indicator. In megger it s good with infinity or it must be minimum 100M OHM, IF IT SHOWs 50 it could be coz of moisture in winding by heating the alternator the insulation resistance value may improve
insulation tester (Megger) can used to checked the short circuit on HV side. HI POT tester is also a means to checked the shot circuit in HV cable.
Insulation resistance test: This test is used to find the insulation resistance of motor for 1 min or 10 min through high voltage insulation tester. By this we can find the insulation level. Polarization index: This is the ratio between insulation resistance for 10 min to insulation resistance for 1 min.
The insulation resister tester was invented by Ohm and was instantly the industry standard when dealing with testing the safety and effeciency of electrical products according to the Electrical Construction & Maintenance web site ecmweb.

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.

A hardness tester is a device for measuring the hardness of a material defined as its resistance to indentation. It can be found in your local science and laboratory supply shops or any store that sells science and lab kids as it's often used in scientific research.
A LAN tester is a circuit used to check the LAN cables. They run for approximately $41.00 in most electronic stores.
footing resistance is that resistance which could not harm human body while touching tower...and it is calculated by earth resistance tester
ln reverse biase high resistance and in forward biase very low resistance
An insulation tester is a required accessory for a professional battery shop. They can be found online as easily as checking out sites like Amazon or eBay.
