Abstract :
In order to determine whether a machine is experiencing shaft voltage and current problems, recognition of the four types of damage is imperative. The four shaft voltage sources and their means for generation are discussed in detail. Methods for correction and/or elimination of these sources are reviewed so that users can better understand how these voltages and currents are generated. Testing for the detection of shaft voltage sources and their potential circuits are outlined
