What is the maximum insulation resistance reading on a 800A busbar?
infinite
What is difference between insulation resistance test and polarization index?
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.
What is excessive electrical resistance?
High resistance means insulation
What happens to insulation resistance when increasing cable length?
The insulation resistance remains the same throughout the entire length of the conductor.
What is insulation megger draw and explain with neat diagram?
Meggar is a hand driven tool for measuring insulation resistance and earth resistance.

What is isolation resistance?
I think you mean, 'insulation' resistance! It's the resistance of insulation, normally expressed in megohms.
What test would identify a short circuit in a lighting circuit?
earth continuity insulation resistance polarity
Between what values should the safe reading of insulation resistance of a domestic house?
Between .5 meg ohms to 2 meg ohms is a safe range for your house wiring insulation. Infinity is the ultimate.
What is excessive electrical resistance?
High resistance means insulation
What happens to insulation resistance when increasing cable length?
The insulation resistance remains the same throughout the entire length of the conductor.
What is dielectric absorption ratio?
This is a test usually used when performing a insulation resistance on a transformer. This test (result) can be optained by deviding the 30 sec reading into the 60 sec reading. This test recognizes the fact that "good" insulation will show a gradually increasing IR after the test voltage is applied.
What is meggers?
A megger is an electrical instrument that is used to measure the resistance of insulation by applying a DC voltage to the conductor. One lead is connected to the conductor and the other lead is connected to ground. Safe insulation reading to ground should be above 2,000,000 ohms or 2 megs.

Meggar is a hand driven tool for measuring insulation resistance and earth resistance.
Why the load must be removed when to conduct the insulation and resistance testing?
explain why all the load must be removed when to conduct the insulation and resistance testing
How insulation resistance of a motor winding checked If the insulation resistance is low What is likely to cause?
