FIELD: electricity.
SUBSTANCE: monitor comprises two sensors sensing the strength of an external magnetic field, which are placed at current feeding and draining wires coupling the load to a single-phase bridge rectifier. At that outputs of sensing elements of the field strength sensors are connected to the first and second input of the comparator respectively through the relevant analogue amplifiers and narrow-band filters, while the output of the comparator is coupled to an indicator.
EFFECT: potential identification of leakage current in the load of a single-phase bridge rectifier by a non-contact way in real time without the disconnection of the rectifier from the functioning process.
