This guide discusses and recommends analytical test and evaluation procedures for acceptance and use of conventional petroleum (mineral) dielectric oils. Minimum standards, methods of maintenance for these fluids and levels at which these methods become necessary and included. The mineral oils covered in this guide are used in transformers, voltage regulators, switchgear, reactors, circuit breakers and load tap changers. The Characteristic of the oils discussed in this guide does not include oil that is in factory fill lines nor does this guide cover reclaimed oil installed in new equipment. The qualities of such oil, if used, should be agreed upon by the manufacturer and the user of equipment.
