Abstract
New data on the rate of deterioration of cellulose insulation at different temperatures have been obtained. From them a table of time periods and temperatures has been made at which oil-insulated transformers may be operated in order that specific cellulose insulation strengths of approximately 65 per cent of the original value may be maintained. It is expected that this value will be maintained even after operation of a considerable length of time at 105 degrees centigrade.
