PD IEC/TR 61946 is a technical report about mineral insulating oil.
PD IEC/TR 61946 provides test method regarding the classification of mineral insulating oils as either paraffinic or naphthenic, by means of low-temperature differential scanning calorimetry (DSC).
PD IEC/TR 61946 outlines that the method is applicable to mineral insulating oils obtained from petroleum crudes. PD IEC/TR 61946 is also applied to mineral oils containing pour point depressants, as these additives do not prevent the formation of paraffin crystals but only the growing of such micro-crystals.
PD IEC/TR 61946 on mineral insulating oils is useful for:
PD IEC/TR 61946 provides guidelines to manufacturers on how to distinguish classes of oil to get the best result and safe use.
When these mineral insulating oil are handled according to the standards provided in PD IEC/TR 61946, it ensures smooth workflow and safety.
