Method and device for integrity testing

An automatic data logging kit is used with a hydraulic integrity test kit for testing a liquid cooled stator bar system. The automatic data logging kit includes a spool piece having end connectors (18) attachable between the liquid cooled stator bar system and the hydraulic integrity test kit as well as a plurality of sensor receptacles. At least one temperature sensor (22, 28, 30) insertable within an interior of the liquid cooled stator bar system (SB) is coupled with an output connector (24) operatively securable in the first of the sensor receptacles in the spool piece. At least one pressure sensor (20) is also operatively securable in one of the spool piece sensor receptacles. A control unit (26) receives output from the sensors and calculates a leak rate based on the received sensor output. The automatic data logging kit provides automatic data logging capabilities for pressure-decay and vacuum-decay cycle tests, increased accuracy of the pressure-decay and vacuum-decay data and reduced cycle time in determining the leak rates.
