FIELD: protection of electrical equipment; protection of switchgear lead-in components and step-down transformers. SUBSTANCE: switchgear disconnection occurs as soon as sum of two quantities proportional to current and voltage vectors of combined components goes beyond setting value. EFFECT: improved sensitivity of protective gear throughout entire range of probable short-circuit currents, improved fire safety of cable lines, simplified design of protective gear. 2 dwg
