Generator Expert : Thomas Laird

About Thomas Laird

I have over 35 years working on generators in the power generation industry. My experience began with 12 years with Siemens Power Systems (formerly ACPSI). In 1993 I accepted a position as a generator specialist with ABB which became Alstom Power. In 1997 I created an onsite generator monitoring program called GOLD (Generator On-line Diagnostics). I’ve published several papers concerning generator diagnostics and condition based maintenance. I worked briefly at MD&A but returned to Alstom in 2005. In 2013 I transferred to PSM to work in the Shaft Line group. I currently hold the position of Principle Engineer, Electrical Systems at PSM.

General comments and observations

I’ve worked on all types of generators manufactured by GE, Siemens, Westinghouse, KWU, ABB, Alstom, and Brush from nuclear plants, coal, and combined cycle. I also have experience with static and brushless excitation systems, generator protection, and SFC/LCI.

  • Stator windings
  • Stator core and frame
  • Excitation systems
  • Vibration
  • Failure root cause
  • Inspection
