Flux monitoring via air gap flux probes is a proven technology used for many years in synchronous machines to determine the presence of turn-to-turn shorts in a rotor winding. This information is critical in planning maintenance outages and augmentin

On-line partial discharge (PD) measurement is now widely applied to motors rated 6 kV and above that are fed from the 50/60 Hz power system. However, during the past several years, many motors are being powered from inverters which facilitate variabl

In an attempt to study Giardia at the DNA sequence level, the rRNA genes of three species, Giardia duodenalis, Giardia ardeae and Giardia muris were cloned and restriction enzyme maps were constructed. The rDNA repeats of these Giardia show completel

Random wound stator windings in motors operating in refining and petrochemical plants have failed when exposed to the fast-risetime voltage surges coming from inverters. Studies show that the failure is due to a combination of bad luck in specific mo
