适用范围：The scope of this guide includes general philosophy, practical applications, and economic considerationsinvolved in power transformer protection.Emphasis is placed on practical applications. General philosophy and economic considerations inprotecting transformers are reviewed. Types of faults in transformers are described. Technical problemswith the protection systems, including the behavior of current transformers (CTs) during system faults, arediscussed. Associated problems, such as fault clearing and reenergization, are discussed as well.
