Safety of transformers, reactors, power supply units and similar products for supply voltages up to 1100 V - Particular requirements and tests for auto transformers and power supply units incorporating auto transformers1 Scope Replacement: This part of IEC 61558 deals with the safety of auto transformers for general applications and power supply units incorporating auto transformers for general applications. Transformers incorporating electronic circuits are also covered by this standard. NOTE 1 Safety includes electrical, thermal and mechanical aspects. Unless otherwise specified, from here onward, the term transformer covers auto transformers for general

— Ratings of maximum potential difference and electric current are not dealt with in this standard because the behaviour of a high-voltage cable plug and socket connection depends on the materials of the cable termination plug assembly and the receptacle socket assembly

which are indispensable for securing a basic level of performance and obtaining essential data on cells for various designs of battery systems and battery packs
