Proposed Guide for Calculating Losses in Isolated-Phase Bus

The proposed guide forms a useful document for those responsible for evaluating losses in isolated-phase bus. The Working Group plans two modifications in the final version of the guide. The first is an extension of Fig. 1 to make it more useful in the calculation of skin effect of very large enclosures. The second modification will be the inclusion of an empirical formula for more accurate determination of the K factor to be used in determining losses in continuous bus enclosures. The fomula will be based on test data reported in [6].
