BS EN 60599:2016 PDF Download

The BS EN 60599:2016 standard provides guidance on how to interpret dissolved and free gas analysis in mineral oil-filled electrical equipment. The standard is applicable to equipment that is filled with mineral insulating oil and has solid insulation made of cellulosic paper or pressboard. It includes various types of equipment such as transformers, reactors, bushings, switchgear, and oil-filled cables. However, it should be noted that the standard should be applied with caution to other liquid-solid insulating systems.

The main objective of this standard is to assist in diagnosing the condition of the equipment and determining necessary maintenance or future actions based on the concentrations of dissolved and free gases found in the oil. However, it is important to note that the indications obtained from the analysis should be viewed only as guidance, and any resulting actions should be carried out with proper engineering judgment.
