Generator Shaft Current at Cecil Tucker blog

Generator Shaft Current. Static discharge resulting from flow. Shaft currents result from the buildup of electric charges on the machine shaft through 3 mechanisms: There has been an increase in occurrences and intensity of shaft current damages as machines became larger, particularly on high speed turbo. A shaft current alarm is indicating that arcing is present between shaft and bearing surfaces, in special cases also in couplings and. The purpose of shaft monitoring is to indicate the presence of high levels of voltage or current on the motor or generator shaft in order to detect poor. By monitoring shaft voltage and current on both ends of the rotor, our ghm rotor shaft voltage module delivers reliable assessments of your generator‘s. As “foe”, they can, as a minimum, generate circulating currents, reducing unit efficiency and, as a maximum, the generated current can damage. Current and voltage values •“normal” shaft currents can range from a few milliamps to several amps •voltage higher than 10 v considered to be.
