Control system reliability can be a matter of skilled routine maintenance activity and proficient troubleshooting capability.  Availability and reliability can be affected by the quality of service performed by maintenance personnel.  This Seminar is specifically directed to assist these personnel in the accomplishment of this important goal.

Learn to use effective routine maintenance and calibration procedures.  Learn what checks can be performed on-line and how to safely perform these checks.  By understanding the major signal control paths (and the “big picture”) you will increase the likelihood of accurate problem analysis.  Learn how to quickly determine whether the problem is likely electrical, mechanical or hydraulic.

Topics include: Turbine Steam Valves and Actuator • System Operation • EH Fluid• Auto Stop • Speed Control • Load Control • Tracking • Throttle Valve Control • Governor Valve Control • OPC, LDA, AGG • Servo Amplifiers • Trip System • Card and System Calibration • Troubleshooting

HPC is prepared to instruct this Seminar as developed by equipment-experienced instructors. Troubleshooting experience is given. The instructional experience is unmatched. The dedication to our accomplishing stated Seminar objectives are a matter of policy.  The Seminar is recommended for Engineers and E&I Technicians.
