Course Objective

To obtain an understanding of how to troubleshoot, maintain and improve GE Gas Turbine (GT) operation using the GE Speedtronic™ Mark V (mk5) Turbine Control Panel (TCP).

Course Description

Covering the fundamentals, architecture, software, operation, and maintenance of a mk5, the course introduces the GT major components, associated systems, and TCP preparation for operation. The Case studies resulted from actual customer questions and remote support calls resolved by GTC. The Cases provide a unique insight, and understanding with direct application, as practical tips, or potential enhancements.

For courses delivered at our Hawthorne, NY Training Center, we utilize our energized Mark V panel and our custom built simulator. For Customer Site training, we utilize only our simulator.
