摘要
An Advanced Data Logging kit for testing a generator's liquid cooled stator bar system (15) for leaks is disclosed. The kit is installed in between the generators header (14) and the HIT Skid and in the generator's cooling system (17). The kit includes pressure and vacuum transducers (34), sensor arrays (50) with thermocouples, and data acquisition circuits. The sensor arrays (50) are used to plumb the thermocouples into the generator's header (14) and cooling pipes (17). The pressure and vacuum transducers (34), and the thermocouples in the sensor arrays (50), 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 (15) exists. A computer (16) included in the kit has the ability to analyze the data readings, perform calculations, and predict leak rates in the stator bar system (15).
