FIELD: transport.
SUBSTANCE: invention relates to railway various purpose transport facilities and can be used for revealing drive wheel stalling by the presence of metallic dust in the zone of the wheel-to-rail contact. To detect the metallic dust, air from the said contact zone is drawn by the fan into air box housing electrodes with a discharge gap supplied with high-voltage pulses. Given the metallic dust, air gap is broken down which is detected by the electrode circuit current pickup signaling the stalling conditions.
EFFECT: simpler design and higher reliability.
