One of the most important but underestimated factors impacting the operation of turbines (both steam and gas) and other machinery is the condition of the oil, especially its “mechanical” cleanliness (presence of solid particles). Although the need for appropriate oil care is commonly accepted among power plants with regular maintenance -
