CONTROL OVER FALSE INTERRUPTION AND SUCCESSFUL AUTOMATIC RECLOSURE OF MASTER INTERRUPTERS OF SUBSTATION ELECTRIC POWER TRANSMISSION LINES Russian patent published in 2015 - IPC H02J13/00

Abstract RU 2551667 C1

FIELD: electrical engineering.

SUBSTANCE: in case short-circuit current does not exist and working current does not decrease by magnitude defined by load of one of power transmission lines up to increase in working current defined by loading of said line, time is measured and compared with automatic reclosure release time of all master interrupters. In case measured time equals that of one of master interrupters conclusion is made about false interruption and subsequent successful reclosure.

EFFECT: enhanced possibilities of control.
