Measuring insulation resistance, why is the greater the voltage, the greater the insulation resistance?
You said that the standard of insulation resistance is that the higher the voltage, the greater the required insulation resistance. General requirements >1M/KV.
Plus voltage, insulation resistance will certainly be large, that is to do pressure test will appear.The general shake table, insulation good, the pointer will point to infinity.
No, the dielectric resistance of the dielectric itself does not increase with the applied voltage. On the contrary, when the applied voltage is greater than the dielectric strength of the dielectric itself, the dielectric will break down.
