Monitoring Technologies

Through unique monitoring technologies, Mitsubishi Power 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 Mitsubishi Power to predict unexpected failures, as well as devise and implement systematic maintenance.

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