286-1968 - IEEE Recommended Practice for Measurement of Power-Factor Tip-Up of Rotating Machinery Stator Coil Insulation
Standard Details
The procedures described in this Recommended Practice are applicable to stator coils designed for use in rotating machinery which operates at a system voltage of 6600 volts or higher. 2.2 The coil insulation under consideration is principally the major ground-wall insulation which is external to the conductor structure. Only that part of the strand and turn insulation which is dielectrically in series with the ground-wall insulation enters into the measurements
