FOREWORD
1 General
2 Characteristic properties of different three-phase
winding combinations and magnetic circuit designs
3 Characteristic properties and application of auto-
connected transformers
4 Zero-sequence properties - neutral load current and earth
fault conditions, magnetic saturation and inrush current
5 Calculation of short-circuit currents in three-winding,
three-phase transformers (separate winding transformers
and auto-connected transformers) with earth neutrals
6 Parallel operation of transformers in three-phase systems
7 Calculation of voltage drop for a specified load,
three-winding transformer load loss
8 Specification of rated quantities and tapping quantities
9 Convertor applications with standard transformers
10 Guide to the measurement of losses in power transformers
Annex A Basic relations for single-phase and two-phase
earth faults
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.
