If the insulation strength is high, value of R will be low and if the insulation is weak the IR will be low with high current. Factors that affect the Insulation resistance Conductive leakage current (IL) Conductive current is a small (micro-amp) amount of current that normally flows through insulation, between conductors or from a conductor to ...
Apr 20, 2020· Insulation is normally measured by its thermal resistance, also known as the R-Value. Your house will have better insulation if the insulation has a high R-Value. To keep your home warm in the winter season, your attic requires a minimum of R-49 insulation .
Apr 29, 2012· IR Value for Transformer Insulation resistance tests are made to determine insulation resistance from individual windings to ground or between individual windings. Insulation resistance tests are commonly measured directly in megohms or may be calculated from measurements of applied voltage and leakage current.
Sep 01, 2005· Temperature measurements are employed for research into the mechanics of grinding and for process monitoring. Temperature measurement in grinding presents a number of challenges particularly in High-Efficiency Deep Grinding .
Feb 24, 2014· I pat tested my washing machine at home yesterday and it's failing the insulation resistance test, giving a reading of 0.87 Mohm. After some investigating, I found that by unplugging the drain outlet pump, the insulation resistance .
During this interval, the resistance should drop or remain relatively steady. Larger insulation systems will show a steady decrease, while smaller systems will remain steady because the capacitive and absorption currents drop to zero faster on smaller insulation systems. After one min, read and record the resistance value.

Apr 16, 2020· The measurement of insulation resistance is carried out by means of a megohmmeter – high resistance range ohmmeter.This is how the test works: DC voltage of 500 or 1000 V is applied between the windings and the ground of the motor. Ground insulation .
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 .
The required formula is – R=1+V, Here R=resistance in mega ohm(MΩ), V= equipment rated voltage in KV. So if we like to check a machine rated voltage is 11 KV, the minimum tolerated insulation resistance will be R=1+11=12MΩ, and for a motor with 220 voltage rating the IR value will be R=1+.220=1.2MΩ.
