BENCH FOR ELECTRIC, THERMAL AND BARO TESTING OF DOWNHOLE DEVICES UNITS Russian patent published in 2011 - IPC G01M10/00 G01R31/00 

FIELD: physics.

SUBSTANCE: bench for electric, thermal and baro testing of downholde devices units includes a power supply source, a package of electric metres and a testing chamber limited from butt ends with insulating units with sealing elements contacting the inner surface of the camber the inner cavity whereof is connected to a pressure source, a static pressure registration transducer and a vessel with operating medium via a channel and a pipeline system. The power supply source is represented by a high constant or pulse voltage generator. The insulating units are made of metal representing an integrated structural element wit fixture element on the butt end surface and sealing elements arranged on the lateral surface of the insulating unit part inserted into the chamber cavity. The electric meters package additionally contains a capacitive or a potentiometre-type voltage divider, a Rogowski coil and pulse pressure transducers.

EFFECT: test bench functionalities extension and improvement of accuracy and reliability of electric, thermal and baro testing of electrode systems of downhole electrohydraulic apparatus.
