Cleaning Effect for Oil in Oil Impregnated All-film Capacitors
2006 IEEE 8th International Conference on Properties and applications of Dielectric Materials, 2006Loss tangent (tandelta) is an important parameter for designing oil impregnated all-film shunt capacitor. To obtain low tandelta, tandelta of film and oil should be low. But in our study model capacitors of low tandelta are obtained using oil of high tandelta. Accelerated aging test and partial discharge (PD) measurements are carried out on these model

In Chap. 6 relationships were given, on the basis of certain assumptions, between radial movement of the journal and the accompanying force. Accordingly, an oil-film bearing can broadly be described as a spring-damper element, with the special property that the displacement and the force in general do not occur in the same direction. In comparison with

Low frequency conduction in oil films and oil-impregnated papers
Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1973, 1973In dielectric materials, measurements of the low frequency ac conductivity can often reveal certain features of the electrical conduction mechanism which are often not apparent from the data derived through dc or higher frequency ac measurements alone.

Film thickness anomalies in very thin elastohydrodynamic oil films
1997Experimental studies of very thin elastohydrodynamic (EHD) oil films have shown, or suggested, that several aspects of lubricant behaviour do not fully conform to the model presumed by classical EHD theory. This study examines three forms of behaviour which appear to be anomalous.

Consequences of oil film degradation
2017In a review of recent studies into two-stroke lubrication, Rathesan Ravendran and Peter Jensen of Hans Jensen Lubricators highlight the importance of cylinder oil distribution.
