Abstract

This part of IEC 60076 applies to three-phase and single-phase power transformers (including auto-transformers) with the exception of certain categories of small and special transformers such as: – single-phase transformers with rated power less than 1 kVA and three-phase transformers less than 5 kVA; – transformers, which have no windings with rated voltage higher than 1 000 V; – instrument transformers; – traction transformers mounted on rolling stock; – starting transformers; – testing transformers; – welding transformers; – explosion-proof and mining transformers; – transformers for deep water (submerged) applications.
