摘要： The invention relates to a method for recognising a symmetrical short-circuit in a power supply network, wherein with a first protective device (15d) a first section (C) of the power supply network is monitored for a symmetrical short-circuit and with a second protective device (15a) a second section (A) is monitored for a symmetrical short-circuit, wherein the second protective device (15a) is arranged as a reserve protective device so that when a symmetrical short-circuit in the first section (C) is recognised, after a predetermined lag time has elapsed it emits a shut-off command to a power switch (14a), and wherein an oscillation recognition unit (24) is provided which emits an oscillating signal which blocks the emission of the shutoff command by the second protective device (15a) if an oscillation in the power supply network has been recognised. In order to provide a possible means by which external symmetrical short-circuits can be disconnected independently of an occurring oscillation, according to the invention in the case where the second protective device (15a) has recognised a symmetrical short-circuit in the first section (C), before the oscillation recognition unit (24) has recognised an oscillation in the power supply network, the shut-off command is emitted independently of the presence of an oscillating signal if the lag time has elapsed.

摘要： The invention relates inter alia to a method for monitoring a resonant-earthed three-phase power transmission system (40), or a three-phase power transmission system (40) which is isolated from earth potential, for the presence of an earth fault. The invention provides for a check to be carried out to determine whether the line-to-line phase voltages of the power transmission system exceed a predetermined amplitude-related unbalance threshold relative to one another, for a corresponding balance signal to be formed which indicates balance or unbalance, and for this balance signal to be used for monitoring from then on.

摘要： The invention relates to a method for monitoring an electrical power supply system, wherein a first protection device (13a) is connected to a first line (11a) of the power supply system for detecting measured values characterizing the operating state of the first line (11a), and wherein the first protection device (13a) is connected to an adjacently arranged second protection device (13b) via a communications link (15). In order to further increase reliability and selectivity when monitoring parallel lines, the invention proposes a method in which the second protection device (13b) is connected to a second line (11b), which runs in parallel with the first line (11a), the two protection devices (13a, 13b) exchange the measured values detected thereby with respect to the respective line (11a, 11b) thereof and/or signals derived from said measured values with one another, each protection device (13a, 13b) is designed to perform a protective function for the respective line (11a, 11b) thereof whilst implementing a main protection algorithm (25), and each protection device uses the measured values detected at the dedicated line (11a) and the measured values and/or signals received by the other protection device (13b) for implementing the main protection algorithm (25) of said protection device. The invention also relates to a protection system and a corresponding protection device.
