Grinding Machine Insulation Resistance Value. Use 500 v insulation resistance meter test, the insulation resistance should not be less than 5 m Ω, if less than this value, should open the drain and vent hole, drying or drying after use. 2, check the valve grinding machine vent, water hole, oil hole and cable joint sealing is loose, if
Insulation resistance measurement is based on Ohm's Law. By injecting a known DC voltage lower than the voltage for dielectric testing and then measuring the current flowing, it is very simple to determine the value of the resistance. In principle, the value of the insulation resistance is very high but not infinite, so by
Insulation resistance is the most typically measured parameter to determine the overall health of electrical insulation. Concerning cables, the IR differs from one cable to another depending upon the cable's length, type of cable, and insulation thickness.

insulation (resistance decreases in temperature or moisture). With a little record-keeping and common sense, however, you can get a good picture of the insulation condition from values that are only relative. The Megger insulation tester is a small, portable instrument that gives you a direct reading of insulation resistance in ohms or megohms ...
To give you the correct answer I need to find the old Megger insulation testing booklets I bought via Ebay some years ago. First off there isn't a 1 Mohm minimum insulation resistance for an existing installation, when you are preparing an Electrical Installation Condition Report you need to make an engineering judgement as to whether the insulation resistance test result is acceptable; and it ...

Insulation Resistance Tests must not be carried out using Ohmmeters or Multimeters because these meters only produce a small battery voltage in the region of 1.5 to 9 volts. This small voltage is insufficient to pressure test the insulation to expose any weakness in it and therefore is totally inappropriate for Insulation Resistance Tests.
