Revision Standard – Superseded. A uniform method by which the thermal endurance of electrical insulation systems for dry-type specialty and general-purpose transformers can be compared is established. These insulation systems are intended for use in the types of transformers described in NEMA ST 1-1988 and NEMA ST 20-1992.<\/p>\n
