摘要： For filtering off of low frequency and a periodic transient phenomena in relay protection devices for electric high voltage networks, the signals of which occur in the event of a fault in the network and which are superimposed on the signals supplied to measuring relays arranged in the relay protection device, a normally short-circuited filter is included in a normally open alternative path for the measuring signal which is parallel to a part of the normal signal path. A supervisory circuit includes a time circuit, a fast fault indicator and an undervoltage detector. A signal from the fault indicator breaks the short-circuit of the filter and, upon a signal from the undervoltage detector, connects the filter in the path of the measuring signal. The measuring relay is blocked during a time interval which is equal to the difference between the pulse time of the time circuit and the time of operation of the undervoltage detector. This is accomplished by an AND-gate which has its inputs connected to the fast fault indicator and to the undervoltage detector and its output connected to a make-and-break contact for closing the alternative current path.

摘要： A method and a device for identifying, when a fault has been detected in a power network, single-phase to ground faults by determining for each phase an auxiliary current based on the present phase current, ground fault current and ground current. If the difference between two consecutive, calculated values of the auxiliary current in some phase is smaller than a predetermined limit value, this means that there is a single ground fault in this phase.

摘要： An antenna device for transmitting and receiving radio frequency waves, installable in a communication device includes an antenna structure switchable between antenna configuration states. Each state is distinguished by a set of radiation parameters, such as resonance frequency, input impedance, bandwidth, radiation pattern, gain, polarization, and near-field pattern. A switching device selectively switches the structure between the states. The antenna device includes a first receiver which receives a first measured operation parameter indicative of quality of transmission of radio frequency waves by the antenna structure, and a second receiver which receives a second measured operation parameter indicative of quality of reception of radio frequency waves by the structure. The antenna device includes a controller which controls the switching device, and selective switching of the antenna structure between the states, based on the first and second measured operation parameters, to improved transmission and/or reception quality.
