METHOD AND DEVICE FOR SUPPLYING AT LEAST ONE ELECTRICAL CONSUMER OF A DRILL PIPE WITH AN OPERATING VOLTAGE

摘要

In a method and device for supplying at least one electrical consumer (10) of a drill pipe with an operating voltage, at least one electrical component (10, 11, 15) on pipe rods (6) of the drill pipe is tested for defects with a test voltage that is smaller than the operating voltage before the operating voltage is applied, and the operating voltage can only be applied when no defects are present.
