Abstract: An Advanced Data Logging kit for testing a generator's liquid cooled stator bar system for leaks is disclosed. The kit is installed in between the generator's header and the HIT Skid and in the generator's cooling system. The kit includes pressure and vacuum transducers, sensor arrays with thermocouples, and data acquisition circuits. The sensor arrays are used to plumb the thermocouples into the generator's header and cooling pipes. The pressure and vacuum transducers and the thermocouples are used to collect pressure, vacuum and temperature data that is used to conduct a Pressure Decay Test and a Vacuum Decay Test to determine whether or not a leak in the liquid cooled stator bar system exists. A computer included in the kit has the ability to analyze the data readings, perform calculations, and predict leak rates in the stator bar system.

Abstract: A method of sealing a generator stator bar and a stator bar end fitting receiving the end including the steps of: brazing the fitting to the end of the stator bar with a braze material; applying a powder coating material to the end of the stator bar in the fitting; and curing the powder coating material to form a barrier coating on the end of the stator bar and the adjoining interior surfaces of the fitting.

Abstract: Systems and methods are provided for measuring pressure on a member. The systems and methods include exciting the member to create a vibratory response in the member and detecting the vibratory response. The vibratory response is then compared to at least one of a plurality of previously recorded vibratory responses of the member. The pressure on the member is then estimated based on the comparison of the vibratory response to the plurality of previously recorded vibratory responses.
