LINE DAMAGE DETECTOR Russian patent published in 2014 - IPC G01R31/08 H02H5/10 H02H7/26 

FIELD: electricity.

SUBSTANCE: invention is related to the field of electric engineering and can be used in the fault detection system in order to detect a fault or damage at an electrode line in HVDC system. Technical result lies in improvement of the system reliability at damage detection. The electrode line contains the first and second branches connected in parallel. The fault detection system contains the first and second pulse generation schemes intended to generate electric pulses for the first and second branch respectively and also the first and second current measurement devices capable to generate signals specifying the electric signals in the first and second input lines respectively.

EFFECT: possible independent generation of electric pulses for the first and second branch respectively and independent recording of the first and second signal structures that represent electric signal in the first and second input lines respectively, increase in information content of the collected data thus ensuring more reliable analysis of damage occurrence in the electrode line.
