Power transformer is the most exorbitant and controversially the most essential equipment. Insulation abortion in transformer can cause stretched term interruption to supply and loss of revenue and the important maintenance procedure. The power transformer consists of organic insulation like Mineral oil, pressboard and paper. In impecunious of bio- degradability and availability, ester oil is replaced by Mineral oil. The partial discharge is a tool for evaluate the insulation atrophy of dielectric materials. In this paper the results of a laboratory based experimental investigation of partial discharge activity in oil – impregnated paper. To guesstimate the statistical parameter for different electrode configuration like different configuration under open air gap condition.

Abstract The reluctance network model of a permanent magnet tubular motor (PMTM) has been presented in the paper. The reluctance values of the magnetic circuit have been calculated with using analytical expressions. The air gap reluctance has been determined with using both analytical expressions and the finite element method (FEM). Using the calculation model, the flux values coupled with the windings have been obtained and used in the calculations of force value. The calculated results have been compared with numerical and measured ones.
