Abstract :
The insulation resistance of oil-impregnated-paper sheets has been determined as a function of temperature, dc field application time and test frequency in the range from 1.0 down to 0.01 Hz. The results have shown that if the true dc insulation resistance is to be derived from the low frequency ac measurements, low frequency test data well below 0.01 Hz is required.
