This IEEE Standards product is part of the C57 family on Power Distribution and Regulating Transformers. Abstract: Recommendations regarding oil tests and evaluation procedures are made in this guide;references are made to methods of reconditioning and reclaiming conventional petroleum (mineral) dielectric insulating oils;the levels at which these methods become necessary; and the routines for restoring oxidation resistance, where required, by the addition of oxidation inhibitors. The intent is to assist the power equipment operator in evaluating the serviceability of oil received in equipment, oil as received from the supplier for lling new equipment at the installation site, and oil as processed into such equipment; and to assist the operator in maintaining oil in serviceable condition. The mineral oil covered is used in transformers, reactors, circuit breakers, load tap changers, and voltage regulators. Keywords :insulation testing , load tap changers , oil circuit breakers , oil insulation , power distribution maintenance , power transformer insulation , reactors , transformers , voltage regulators , IEEE C57.106.

Superseded by C57.19.01-2000 Electrical, dimensional, and related requirements for outdoor power-class apparatus bushings that have basic impulse insulation levels of 110 kV and higher are covered. Specific values for dimensional and related requirements that are to be interpreted, measured, or tested in accordance with IEEE C57.19.00-1991 are provided. Bushings covered by this standard are intended for use as components of oil-filled transformers, oil-filled reactors, and oil circuit breakers.

Electrical, dimensional, and mechanical characteristics and certain safety features of single-phase, 60 Hz, mineral-oil-immersed, self-cooled, distribution transformers with separable insulated high-voltage connectors are covered. Ratings, testing, and construction are discussed. These transformers are generally used for step-down pruposes from an underground primary cable supply and are suitable for occasional submerged operation. The intent is to provide a basis for determining their performance, interchangeability, and safety, and for their selection. This standard does not cover the electrical and mechanical requirements of accessory devices that may be supplied with the transformer.

The standard test procedure for the thermal evaluation and qualification of electrical insulation systems (EISs) for random-wound ac electric machinery, where thermal degradation is the dominating aging factor, is described. The relative thermal performance of a candidate EIS is compared to that of a reference EIS. Insulation systems for such machinery with input voltage of up to 600 V at 50/60 Hz are described in this standard. A statistical method for establishing a relative life-temperature relationship for an insulation system is also described. To have any significance, the reference insulation system must be supported with adequate field service data. Evaluation of insulation systems for use in air-cooled, random-wound ac electric machinery with usual service conditions is this procedure s intent. This procedure, on its own, does not cover insulation systems such as exposure to conducting contaminates, radiation, inverter applications, or operation in oils, refrigerants, or other media that potentially degrades insulating materials.
