A leak detection system includes a testing interface, which includes a rotation holder configured to retain and rotate a package. The testing interface includes a plunger apparatus configured to actuate a plunger to apply a pressure to the package before and/or during the package being inspected using a high voltage leak detection (HVLD) apparatus. The testing interface also includes a controller configured to operate and coordinate the operation of the testing interface with operation of the HVLD apparatus.

The present invention relates to a flexible tape (41;50) for use in detecting liquid leaks comprising an elongated substrate (44), having a length (L), a top surface (44a) and a bottom surface (44b), formed from a moisture absorbent material. The flexible tape further comprises at least one non-moisture absorbent electrically insulating material (45.46; 52) disposed on the top surface (44a), and first and second electrical conductors (47,48) spaced via the electrically insulating material (45,46; 52). The invention also relates to a leak detection system (80) and method for detecting a presence of an electrically conductive liquid.

A scour monitoring system may provide a housing that is separated into multiple segments that are fluidically isolated from each other. The scour monitoring system may be position adjacent to a structure to be monitored for bridge scouring. Each of the segments may provide a water-swellable material positioned near or in contact with a fiber Bragg grating (FBG) cable. If water penetrates a segment, the water-swellable material may expand to deform the FBG cable. The wavelength of the FBG cable may be monitored periodically for changes, thereby providing moisture detection when a change in wavelength is detected.
