New IEEE Standard – Active. A test procedure (Combination of IEEE Std 275-1992 and IEEE Std 429-1994) for comparing two or more insulation systems in accordance with their expected life at rated temperature is outlined. The procedure is limited to insulation systems for alternating-current (ac) electrical machines using form-wound pre-insulated stator coils rated 15000 V and below
