Course Objectives

To enable an engineer to be fully conversant with all aspects of the MK VI Control System and
would have significantly increased confidence/experience in the areas of troubleshooting/fault
finding.

Course Description

The MK VI Speedtronic Control System is a complex and multi-faceted system. This course provides a detailed examination of all the main aspects of the MK VI Control System. This will include MK VI Speedtronic Hardware, Software and a detailed evaluation of Control System Theory/Sequencing. The student will also benefit from a detailed description of troubleshooting techniques and will be allowed to practice these skills with a variety of simulated faults on a Speedtronic Gas Turbine Simulator.

Who Should Attend

This is an essential course for those engineers/technicians involved with the troubleshooting of Gas Turbine faults using a MK VI Speedtronic Control System. On completing this course an engineer would expect to be fully conversant with all aspects of the MK VI Speedtronic Control System and would have significantly increased confidence/experience in the areas of troubleshooting/fault finding. Gas Turbine operators who are looking to advance their career potential would find the course useful and would those Team Leader/Shift Supervisors wishing to increase their knowledge of the MK VI Speedtronic Control system.

Pre-Requisites

All Attendees should have a sound power generation background and have used a MK VI Control
system.

Course Outcome

At the end of this course you will be able to maintain a gas turbine using a MK VI Control System.
