ELECTRICAL EQUIPMENT PROTECTION METHOD Russian patent published in 1997 - IPC

Abstract RU 2093942 C1

FIELD: relay protective gear for electrical equipment, including short-circuit protection. SUBSTANCE: use is made of voltage-response plugging current relay implementing function , where left part of expression is modulus of sum of two quantities; i is imaginary unit; Ir, Kr, Φr are parameters determining, respectively, radius of Ir (A) and coordinates of KrU(A) and Φr (radian) of center of circle of protective gear failure in polar coordinates of protected electrical installation current vector. EFFECT: improved reliability. 2 dwg
