Synthetic organic esters for electrical purposes. Guide for maintenance of transformer esters in equipment Ingestion-build-54371 while boosting their performance1 Scope This International Standard is a guide to the maintenance of synthetic organic esters, originally complying with the requirements of IEC 1099, in transformers with rated voltages up to 35 kV. It is intended to assist the equipment operator in assessing the quality of the liquid during use in the equipment and maintaining it in a serviceable condition. Methods for reconditioning ester transformer liquid are outlined. This standard deals only
