Insulation Resistance Temperature Correction. insulation resistance should be approximately one megohm for each 1,000 volts of operating voltage, with a minimum value of one megohm. Patent granted for new itc. the concept of individual temperature correction (itc) is based on the fact that electrical phenomena in electrical insulation. However, a common rule of thumb is that ir changes by a factor of two for each 10°c change. For example, suppose we obtained an ir reading of 100 megohms with an insulation temperature of 30°c. usually, 20°c or 40°c are used as comparison temperatures; Tables are available for any correction. Safe operation of electrical power network. a temperature correction factor is applied to correct the megohm measurement at present temperature to what it would be at a standard temperature. temperature halves the insulation resistance, while a 10 °c reduction doubles the insulation resistance value. Spot reading test, time resistance test, and step voltage. current temperature correction coefficient method is based on average values at spot temperatures.
