This paper presents a case study in the dangers and consequences involved when the performance of a fast bus transfer scheme becomes unreliable. Current day fast bus transfer system technologies are presented with consideration of replacing an existing system in an operating power plant. Implementation of the new system is presented to provide an(More)

This paper gives the perspective of PacifiCorp's power quality engineer on use of the present IEEE 519 standard as well as the new revisions being proposed for 2005. The existing standard has been very successful in establishing fair limits for both current and voltage distortion. There are just a few difficulties PacifiCorp has had in using 519. Nearly all(More)

This summary paper defines electrical pollution within the context of an electrical power system and draws an analogy between it and air-water pollution. It then describes the principles underlying its prevention. Finally the tools used to predict and design for its mitigation are described. One of these tools, a handheld electrical pollution screening(More)

This paper describes some concepts that could be used to facilitate initial discussion in the updating of a distribution voltage quality standard. IEEE 1250 Guidelines provide an excellent starting point for this effort. Going forward, there is a need to identify typical levels of performance in distribution systems, characterize important factors affecting(More)
