Monitoring Technologies

Through unique monitoring technologies, Mitsubishi Hitachi Power Systems (MHPS) is able to monitor the health of the stator winding ends and rotor winding and deterioration in the stator winding insulation, which have been difficult to monitor under operating conditions. This allows MHPS to predict unexpected failures, as well as devise and implement systematic maintenance.

In addition, to detect looseness in the stator winding, MHPS uses the Digital Wedge Tapper ® developed in-house to quantitatively assess stator wedge looseness.
