FIELD: electricity.
SUBSTANCE: device contains two compensatory type Hall transducers (mounted inside an impedance bond and cut in opposite to each other), a two-input comparator mounted in the relay room an electrical signal tower (one of the inputs connected to the Hall transducers via a cable line while onto the other input of the comparator one supplies reference voltage corresponding to the acceptable level of traction current asymmetry in rail circuits), a signalling device in the form of a light-emitting diode connected to the comparator output; the signalling device is placed on a special panel within the station duty officer quarters; arranged on this panel are light-emitting diodes the number whereof corresponds to that of rail circuits at the station.
EFFECT: extension of functional capabilities of traction current asymmetry determination due to application of compensatory type Hall transducers and their introduction into the impedance bond.
