TESTING THE INSULATION SYSTEMS OF STATOR COILS FOR ROTATING ELECTRICAL MACHINES
23-07-2013
12-01-2013
Specifies the procedures and acceptance limits for testing of insulation systems of stator coils for rotating electrical machines designed to operate at 3.3 kV up to and including 24 kV. The requirements of this Standard are acceptable to form wound coils of single- or multi-stack types for power station auxiliary machines and, as appropriate, to resin-rich and global vacuum pressure impregnated insulation systems. Bars (half coils) such as may be used in machines of turbine driven and hydro-generator types shall comply with ESI 44-7. Appendix A specifies the coil type tests and stator acceptance tests which shall be carried out on machines specified as having sealed windings.
