Abstract
An apparatus and method for identifying liner holidays, with a generator having two contacts with a liner and pulsing current to a moving one of the contacts. A plurality of detected electric signals are processed to continuously generate a baseline indicative of a holiday. A holiday signal is actuated when a signal is detected which when compared to the generated baseline indicates a holiday. A plurality of electric signal types and baselines, such as current strength and voltage, may be separately detected with a holiday signal actuated when either signal type is detected which when compared to its generated baseline indicates a holiday. The moving contact may be flexible to conform to contour of the liner.
