Beginning an analysis of the shortcomings of present methods used to test turn-to-turn insulation of pole coil of large electrical machines
the frequency distribution of the turn-to-turn voltage in pole coil is researched at the first by a distribution circuit model of the pole coil.Appropriate high limit of frequency of the testing voltage source is determined by a circuit simulation analysis made for a typical pole coil.Combining of high power electronic switching technique and parallel resonance skill of...
