MONITORING DEVICE OF LEAKAGE PROCESSES IN CONDUCTOR OF MEDIUM OR HIGH VOLTAGE SYSTEM Russian patent published in 2012 - IPC H02H3/04 H02H3/16 

FIELD: electricity.

SUBSTANCE: monitoring device of leakage processes in conductor (1) of medium or high voltage system includes at least one converter (2, 3) that is designed for determination of current (I) flowing in conductor (1); at that, at least one above described converter (2, 3) is connected to leakage process monitoring device (4). In order to monitor very short-term leakage processes using energy-saving method, invention provides for the fact that between converter (2, 3) and monitoring device (4) there arranged is release device (5) that switches monitoring device (4) from passive mode that does not correspond to monitoring to the active mode corresponding to monitoring when threshold current (I_s) flowing in conductor (1) is exceeded, and that between converter (2, 3) and monitoring device (4) there arranged is at least one scheme (6) of memory device, which stores leakage current (I) subject to monitoring and/or recoding with the monitoring device (4).

EFFECT: improving reliability and economy of device operation.
