Motor Analysis: Stepping Out the Box - A motor analysis team puts an online power analyzer to use where you might not expect it

摘要

Eastman Chemical Co., Kingsport, Tenn., started its motor analysis program in late 1998 when it purchased an online power analyzer. After several months of testing, the company found the analyzer to be limited in its ability to conduct rotor/stator testing at its plant, due in part to the low-level loads found on many of its motors. Power quality testing was also limited at the facility because it produced most of its own utilities, which resulted in good power quality levels.
