Preventing Compressor Bearing Failures with Motor Shaft Grounding
Case Study Summary When routine maintenance revealed electrostatic discharge damage inside a centrifugal compressor, the facility partnered with Rasmussen Air & Gas Energy to identify the root cause, evaluate operational risk, and implement corrective actions to improve compressor reliability and reduce the likelihood of future bearing failures. Using advanced shaft-voltage testing and analysis, Rasmussen Air & Gas Energy diagnosed stray-shaft-voltage conditions on two centrifugal ...
