What is Shaft Condition Monitoring?

A continuous monitoring technology that uses shaft grounding (or earthing) current and voltage profiles under operating conditions to detect existing or developing problems in non-electrical and electrical rotating machinery.

Benefits Of Shaft Condition Monitoring:

Shaft Condition Monitoring offers a means to prevent costly parts replacement from not only shaft current damage, such as frosting, pitting and spark tracking, but of other more serious failures as well. 

Many Case Histories have been reported to MPS, confirming the detection power of this new CBM (Condition Based Monitoring) technology.

• Shaft Rubs
• Wet Steam causing charge separation and possible blade erosion and cavitation.
• Dry Steam with partial admission causing charge separation and spark discharge
• Loss of Shaft Grounding
• Diode Failure in Excitation Surge Suppressor Circuitry
• Torn Copper Leaf Causing Intermittent Ground Fault
• Loss of Shorts in Insulation at Bearings, Seals and Couplings

And we’re sure there are more that have not been reported!

Shaft Condition Monitoring techniques yield “Early Warning” which empowers maintenance personnel to catch the onset of problems and determine incipient failures, long before their effect is made known by temperature and vibration sensors.
