Abstract

Provides information to users of power transformers, complying with the group of publications IEC 60076, i.e three-phase and single-phase transformers including auto-transformers. A part of the information is general, and applicable to all sizes of power transformers. Several chapters concentrate on the specification and utilization of large high-voltage units. Intended to provide information about, service characteristics, system fault currents, parallel operation of transformers, calculation of voltage drop or rise under load, calculation of load loss, selection of rated quantities and tapping quantities, application of transformers of conventional design, measuring technique and accuracy in loss measurement.
