Over the years, the isolated-phase bus has received widespread application in connecting the output of generators to step-up transformers. The trend toward generating units of larger capacity has dictated the need for higher rated isolated-phase bus designs. The increased losses associated with the higher capacity bus may be significant in the economic evaluation of alternate schemes or selection of equipment. The bus designer must know the magnitude and distribution of losses in order to keep temperature rises of bus components within the limits specified in USA Standard C37.20. In addition, the losses must be known to permit proper sizing of forced-cooling equipment whenever it is used.Various papers have been presented that deal with the determination of losses in isolated-phase bus enclosures. The difference in the results obtained for the same bus using various methods is of sufficient magnitude to cause concern. The industry has indicated the need for a guide for calculating losses to establish a common yardstick for establishing, evaluating, and applying different designs.

Practices and requirements for semiconductor power rectifier transformers for dedicated loads rated single-phase 100 kW and above and three-phase 100 kW and above are included. Static precipitators, high-voltage converters for dc power transmission, and other nonlinear loads are excluded. Service conditions, both usual and unusual, are specified, or other standards are referenced as appropriate. Routine tests are specified, and an informative annex provides several examples of load loss calculations for transformers when subjected to nonsinusoidal currents, based on calculations provided in the standard.

Since the first Electromagnetic Nondestructive Evaluation (ENDE) workshop was held in London 1995, the workshops have contributed to the technical advance in ECT through competition and collaboration. This title focuses on 'Eddy Current Testing' (ECT) to identify cracks in metals and alloys.
