Recommendations are made regarding tests and evaluation procedures of insulating liquids; references are made to methods of reconditioning and reclaiming insulating liquids; the levels at which these methods become necessary. The intent is to assist the power equipment operator in evaluating the serviceability of liquid insulation received in equipment, as received from the supplier for filling new equipment at the installation site, and as processed into such equipment; and to assist the operator in maintaining the insulating liquid in serviceable condition. The insulating liquids covered are used in transformers, reactors, load tap changers, and voltage regulators
