VFD Induced Coupling Failure
Abstract
A catastrophic failure of a high performance disc coupling connecting the speed increaser and LP compressor in a VFD controlled 18,300 HP motor/speed increaser/LP compressor/HP compressor train, led to months of reduced plant operation while the root cause of the failure, and corrective action, both outlined in this Case Study, were determined.
