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, programmable Bently Nevada 3300 Monitoring 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 3300 Monitoring System is thoroughly discussed from the aspect of programmable options, calibration, operation, and troubleshooting (interpretation of the front panel LEDs and the error codes). With the added bonus of having a BN 3300 rack (as shown in picture) in the classroom, the requisite skills can be acquired.
With this knowledge, the participant has the information needed to reliably calibrate, maintain, and troubleshoot the Bently Nevada 3300 Monitoring 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.
A topical outline
includes: Review of Steam Turbine Fundamentals, Use and Interpretation of Turbine Supervisory Instruments, Power Supply, System Monitor, Signal Input Relay Module, Dual Vibration X/Y Gap Monitor, Maintenance and Calibration Issues.
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.
Upon completion of this course the participant will be able to:
- Explain how the turbine expands and why this is important.
- Explain the purpose of each turbine supervisory instrument.
- State the general physical location of each turbine supervisory instrument.
- Name the components along with their location that make up the BN 3300 Monitoring System.
- Identify the proper programming configuration within the Power Supply in selecting the required transducer voltage and the data communication interface.
- Describe the functions associated with the System Monitor.
- State the programming requirement between the Power Supply module and the System Monitor module.
- Identify the module to which the signal from the transducer is wired.
- State the difference between a Dual Relay and Quad Relay within the Signal Input Relay module.
- Identify the proper programming configuration within the Signal Input Relay in selecting the proper functionality of the ALERT and/or DANGER Relay.
- Explain the condition that represents the status of the LEDs when given a snapshot of the front panel LEDs on the Dual Vibration XY/Gap Monitor.
- Identify the proper programming configuration when given specified user‑define features for the Dual Vibration XY/Gap Monitor.
- Explain the programmable option Trip Multiply, and state its purpose.
- Identify the error code number that indicates an incorrect jumper configuration on the Dual Vibration XY/Gap Monitor.
