Scope

This standard specifies the test methods and limits for measuring the dielectric loss tangent of a single stator coil (bar) of a rotating electrical machine. This standard is applicable to the measurement test of dielectric loss tangent of Class B and Class F insulation dielectric loss tangent of stator coils (bars) of synchronous generators, synchronous condensers and AC motors with rated voltages of 6kV and above. This standard does not apply to uncured coils (wire bars).
