Dear Sir

Please, let me know what is single effective speed?

I'm working in a gas turbine power plant that uses GE frame 6.
I've found generator vibration setting alarm 7.1 mm/s and trip 11.0 (for single effective speed).
 
Thettin,

Where did you read this description "...for a single effective speed..."?

In the Toolbox or ToolboxST longname description?

In the Control Specification, Sect. 09.nn.nn?

What makes you question the description? Is there nuisance or suspected erroneous vibration alarms/trips?

Lastly, can you say who supplied the Speedtronic (Mark IV, Mark V, Mark VI or Mark VIe)? Was it GE Measurement & Control? GE Oil & Gas? BGGTS? GE Power & Water? GE Energy? Hitachi?
