Turbine leak detection system

Various embodiments include a leak detection system (2) for a turbine compartment (4). In some embodiments, the leak detection system (2) includes: a tracer fluid system (6) fluidly connected with the turbine compartment (4), the tracer fluid system (6) configured to provide an optically detectable fluid (7) to a fluid supply (5a,5b,5c) of the turbine compartment (4); an optical detection system (12) operably connected to the turbine compartment (4), the optical detection system (12) configured to detect the presence of the optically detectable fluid (7) in at least one location (14) of the turbine compartment (4); and a control system (18) operably connected to the tracer fluid system (6) and the optical detection system (12), the control system (18) configured to obtain data about the presence of the optically detectable fluid (7) in the at least one location (14), and provide an indicator indicating a potential leak location based upon the data about the presence of the optically detectable fluid (7) in the at least one location (14).
