Abstract: A system for evaluating bearing metal temperature (BMT) to diagnose rotor misalignment and/or bearing wipe in an electrical machine. A first system is provided that includes: an input system for obtaining bearing metal temperature (BMT) readings from a first BMT sensor located proximate the turbine and a second BMT sensor located proximate the generator, and for obtaining operational data including lube oil inlet temperature, speed and power; a filter system for filtering bad input data; and a misalignment analysis system that issues a misalignment warning in response to one of the BMT sensor reporting an increasing temperature and the other BMT sensor reporting a decreasing temperature.

Abstract: A liquid pressure monitoring system for a circuit of a machine is provided. The system includes a flow meter configured to measure a flow rate of liquid flowing through the circuit, the circuit including a strainer and a cooling section, at least one sensor configured to measure a pressure of at least one portion of the circuit; and a monitoring component for generating an alarm, in response to a value based on the measured pressure exceeding an expected pressure drop, wherein the expected pressure drop is based on the flow rate and at least one flow coefficient.
