Abstract
The present invention relates to a device for analyzing the internal atmosphere of the casing of an electric rotating machine comprising a housing with an atmosphere inlet opening, a suction pump for drawing the atmosphere within the casing of the electric machine, a pump inlet conduit for placing the atmosphere inlet opening in fluid communication with the suction pump, an atmosphere inlet conduit adapted to place the interior of the casing in fluid communication with the atmosphere inlet opening, transducer means adapted to measure the percentage volume of at least one explosive compound present in the atmosphere drawn by the pump and adapted to generate an electric signal proportional to the percentage volume of the explosive compound. The device also comprises comparison means adapted to compare the percentage volume of at least one explosive compound with a predetermined threshold value of percentage volume. The comparison means are also adapted to generate an electric alarm signal when the predetermined threshold value is exceeded.
