FEATURES– Automatic setup from standards or history.
– Report graphically, digital outputs or email.
– Aim to be as sensitive as possible with minimum false triggers.
– Provide trace back to data causing alarm.
– Operator/Expert to decide action.

Machine classification
True multi-parameter state detection
Machine state is a function of current operating conditions as identified by plant process parameters.
For same state we would expect similar vibration.

Benefits
The benefits of continuous monitoring rotating equipment are well known.
PROTOR supports the following:– Analyse bearing performance
– Examination of critical modes Data comparison at know speeds
– More reliable trends
– Ability to set up more accurate limits
– Examination of blade frequencies
– FFT processing of run-up/rundowns
– Historical data storage
– Better control of machine start-up
– Statistical reports on History data

PROTOR helps detect…
With PROTOR operators and experts are better able to detect problems such as:– Shaft unbalance
– Shaft rubs
– Shaft bowing
– Bearing faults
– Misalignment
– Shaft cracking
– Looseness of rotating elements
– Casing Distortion
– Whirl problems
– Balance piston rubs
– Damaged sealing strips
– Generator shorts
– End winding vibrations
– Blade response
– Hub cracking
– Foundation Distortion

Case Studies
Pilot Exciter Bearing Failure– Failure initially detected by fall in 1st Order vibration level.
– Confirmed by corresponding increase in higher harmonics
– Fall in vibration is not always good!
– Boundary alarms detect fall in vibration as well as rise.

Case Studies
Rotor Disk Crack – Slow rise in vibration with
phase change
– Vibration levels not high enough to trigger level alarms. Early detection by vector gradient alarm meant machine taken out of service before catastrophic failure
– Investigation revealed cracked compressor tie bolt
– Decisive, informed action reduced outage time and minimised lost revenue.

Benefit Examples
Generator rotor with axial cracks, 500 MW steam turbine.– Rotors with known or suspected crack condition have been allowed
to run in the safe knowledge that cracks would be detected before they reached a critical size.
Bearing failures, 500 MW IP and exciter rotors.– Having detected and diagnosed a bearing failure the plant was
either allowed to run to a convenient outage or quickly changed preventing secondary damage. Only the affected item needed attention.
Support structure, 200 MW gas turbine– Experience and an understanding of the problem have lead to
modifications at build, reducing a lifetime of vibration sensitivity problems.
