BS EN 60475 is an International Standard. BS EN 60475 is applicable on the procedure to be used for insulating liquids in delivery containers and in electrical equipment such as power and instrument transformers, reactors, bushings, oil-filled cables, oil-filled tank-type capacitors, switchgear, and load tap changers (LTCs).
BS EN 60475 applies to liquids the viscosity of which at the sampling temperature is less than 1500 mm2/s. It applies to mineral oils and non-mineral oils.
BS EN 60475 on the method of sampling insulating liquids is relevant to:
Insulating liquid’s main functions are to protect solid insulation, quench arc discharges, and dissipate heat. Insulating liquids can also act as acoustic dampening media in power equipment such as transformers.
BS EN 60475 provides you with general principles for the sampling of insulating liquids, sampling procedure types, sampling of oil from oil-filled equipment, labelling, and connection between sampling point and sampling device.
Overall BS EN 60475 is beneficial as it provides sampling types and procedures for high specific heat and thermal conductivity tests which demonstrate the performance of insulating materials. The evaluation of these properties provides indications of the right materials to be chosen for your specific application needs.
