METHOD OF OPTICAL RECORDING OF CURRENT TAKE-UP FAILURES Russian patent published in 2019 - IPC B60M1/12 B60L5/00 B60L3/12 G01J1/00 

FIELD: electricity.

SUBSTANCE: invention relates to power supply lines contacting current collectors of transportation vehicles. Method of optical detection of current collection failure consists in the following. Optical radiation is recorded from arc, spark or other discharge or thermal processes, including overload sparking, which occur in current collection faults. Radiation is received in one or more ranges of electromagnetic waves. Then performing the necessary conversion and processing of signals with their subsequent analysis, the result of which is conclusion on one or more of the following parameters: type of discharge or thermal process, which occurred when current collection is broken, duration of discharge or thermal process, energy and/or spectral characteristics of the received radiation.

EFFECT: technical result consists in improvement of authenticity and reliability of determination of current collection fault.
