Smart inspectionThe smart inspection method(mechanization/automation) allows toshorten the conventional inspection periodand inspect equipment.

On line inspectionWe continuously monitor during operation,and analyze the gap with normal time.We conduct abnormality prediction diagnosis.

Because of original vibration analysis technology, the robot is ableto accurately detect the stator wedge tightness in detail.

Inspection Robot

Before:Survey of striking sounds by people (ears)34 days (with removing rotor)

Stator

After:Vibration analysis by machine (robot)6 days (without removing rotor)

Improve generator availability


Inspections with the same precision as people are conducted in a short period of time



Improve energy efficiency and reliability of generators
