BS 5730:2001 PDF

Scope: This British Standard gives guidance on the monitoring and maintenance of the quality of the insulating oil in electrical equipment. This standard is applicable to mineral insulating oils, originally conforming to BS 148, in transformers, switchgear and similar electrical apparatus where oil sampling is reasonably practicable and where the normal operating conditions specified in the equipment specifications apply. The purpose of this standard is to assist the power equipment operator in evaluating the condition of oil in equipment and in maintaining the oil in a serviceable condition. To this end, the standard gives recommendations on standardized tests and evaluation procedures and outlines methods for reconditioning and reclaiming oil. NOTE It is recognized that the oil in certain types of equipment may contain dissolved gases and furanic compounds, the analysis of which may be useful in assessing the condition of the insulation system. The methods of analysis are given in BS EN 60567, BS EN 60599 and BS EN 61198. The interpretation of the results with respect to plant condition monitoring is outside the scope of the standard.
