As professional engineer and middle manager in power generation for 28 years, Ray developed condition monitoring for steam turbines and other plant in several power stations. During 2 years in the UK, he worked with a turbine manufacturer. Advanced condition monitoring methods resulted. His commitment to people training led to joining Monash University in 1992, initially to teach its distance education postgraduate course in condition monitoring(which he still does after retiring from tenure in 2010). In academia, Ray added research to his experiences and presented papers at conferences in Australia and other countries, with many articles in technical journals worldwide. His second book, Predictive maintenance of pump using condition monitoring (Elsevier 2004), gained the George Julius Medal of Engineers Australia for the best publication in mechanical engineering in 2004. This book and his papers gained Master’s degree (MEngSc). His third book was Steam turbine performance and condition monitoring (, 2012). His experience with turbines includes monitoring and solution of performance problems (casing leakage, air in-leakage, blade deposits, blade damage, internal leakage, seal wear) on sets up to 500MW, from different OEMs; solution of vibration problems on small and large machines; investigation of the feasibility of forced steam cooling on3 types of 500MW units; vibration analysis (spectral, phase angle, use of displacement probes) on turbines; investigation and recommendation of TSI improvements to 16MW, 120MW and a 500MW set.
