Insulation Resistance Temperature Correction at Edwin Frost blog

Insulation Resistance Temperature Correction. Tables are available for any correction. Spot reading test, time resistance test, and step voltage. a temperature correction factor is applied to correct the megohm measurement at present temperature to what it would be at a standard temperature. Patent granted for new itc. the concept of individual temperature correction (itc) is based on the fact that electrical phenomena in electrical insulation. usually, 20°c or 40°c are used as comparison temperatures; For example, suppose we obtained an ir reading of 100 megohms with an insulation temperature of 30°c. However, a common rule of thumb is that ir changes by a factor of two for each 10°c change. insulation resistance should be approximately one megohm for each 1,000 volts of operating voltage, with a minimum value of one megohm. current temperature correction coefficient method is based on average values at spot temperatures. individual temperature correction (itc) for insulation resistance measurements. temperature halves the insulation resistance, while a 10 °c reduction doubles the insulation resistance value. Safe operation of electrical power network. For example, a motor rated at 2,400 volts.
