Controlling shaft voltages
Contrary to public belief, the most common electrical phenomenon produced by a power plant's steam turbines, turbine-driven compressors, and pumps isn't sparks or lightning bolts. It's static electricity. The physical effects of static electricity-greater vibration and higher temperatures-can damage bearings, shaft journals, couplings, and gears enough to cause a forced outage. A few inexpensive instruments in the hands of a well-trained technician can prevent "frosting" and "worm tracks" in your babbitt bearings. We'll start the training right now.
