3 days - 1.9 Continuing Education Units Awarded

Why does the turbine expand?  Knowing why and how the turbine expands is invaluable knowledge when it comes to interpreting the information provided by a Turbine Supervisory Instrumentation System.  The modular, software programmable Bently Nevada 3500 Machinery Protection System provides this information concerning not only the expansion of the turbine but vibration as well.  This course provides a thorough working knowledge of the criteria involved in turbine expansion along with the many reasons for abnormal vibration levels, which may not be even related to the bearings.  Once the physical attributes of the turbine are discussed, the Bently Nevada 3500 Machinery Protection System is thoroughly discussed from the aspect of its software programmable options, verification, operation, and troubleshooting.  With the added bonus of utilizing the Rack Interface Software interactive demo, all of the items discussed associated with the configuration of the rack will be reinforced through the visualization of the real-time feedback, thereby providing the potential of having a very pleasant experience when you encounter your Bently Nevada 3500 Machinery Protection System at your workplace. 

With this knowledge, the participant has the information needed to reliably configure a rack, configure the individual modules that make up the rack, and troubleshoot the Bently Nevada 3500 Machinery Protection System.  Additionally, this information enables the participant to qualify the accuracy of the TSI indications to an operator; thereby providing confidence to the operator when important decisions have to be made.

Recommended for technicians, electricians, and/or engineers who have a responsibility to maintain this equipment at any fossil or nuclear turbine generator installation.  Turbine experience is desirable but not necessary.
