Electrical Stress Analysis of High Voltage motor Winding by Switching Surge

  • 발행 : 1993.07.18

초록

Studies have been made to establish what coil design parameters have an important influence on the amplitude of interturn voltages developed in a machine winding subject to steep-fronted surges. The studies are based on a lattice-diagram model of multi conductor transmission line in a machine winding energised by a simple ramp function. Variations in interturn voltages produced by changes in insulation thickness, insulation permittivity, surge wave-front are examined and certain guidelines for avoiding high interturn voltages are evaluated.
