摘要： A shunt assembly for current measurement is formed of a shunt element (12) of substantially cylindrical form and of ZTC material having a pair of current connectors in the form of flat strips (10, 11) attached to its ends. Preferably sensing connectors (13, 14) of the same ZTC material are connected to the ends of the shunt element through holes in the connectors. The sensing connectors may form part of a continuous wire passing through an axial hole through the shunt element. Alternatively, they may be formed as integral extensions of the shunt element.

摘要： An electricity supply network comprises a plurality of intermediate voltage switching and transformer substations (11-1 to 11-3, 12-1 to 12-3) connected together by underground cables. Each cable (22A, 22B) comprises at least one inner conductor and an outer sheath which is connected to the substation housing (20A, 20B). A PLC communication system comprises a plurality of transducers (23A, 23B) coupled to the cables at the substations. Each transducer is located on the side of its cable remote from the sheath connection to the substation housing, whereby the transducer is coupled to both the sheath and the conductor(s) of the cable. We have found that signals are adequately coupled to the cable conductors despite the shielding effects of the sheath. (The prior art technique requires the end of the sheath to be isolated from the housing and earthed by an earthing strap connected to the end of the sheath which is brought back through the transducer to the housing to effectively decouple the sheath from the transducer).
摘要翻译：供电网络包括由地下电缆连接在一起的多个中压开关变电所（11-1至11-3,12-1至12-3）。每个电缆（22A，22B）包括至少一个内部导体和连接到变电站壳体（20A，20B）的外护套。 PLC通信系统包括耦合到变电站处的电缆的多个换能器（23A，23B）。每个换能器位于其电缆的远离护套连接到变电站外壳的电缆的一侧，由此换能器耦合到电缆的护套和导体。我们已经发现，尽管护套具有屏蔽效应，信号也可以充分耦合到电缆导体。（现有技术的技术要求护套的端部与壳体隔离并且通过连接到护套的端部的接地带接地，该接地带通过换能器返回到外壳以有效地将护套与换能器分离）。

摘要： A transducer assembly (16) for an overhead power line operating at intermediate voltage (e.g. 11kV). The power conductor (14A, 14B) passes through insulating means supported by a support rod (17) and generally transversely to the conductor. A magnetic core (26) round the conductor has windings (27) with connections passing (28) along the support rod. The rod may be a transparent tube having inside it a fuse element which produces a distinctive change of appearance when "blown". The insulator may be generally transverse to the conductor (Figs. 1, 2, 3) or generally collinear therewith (Fig. 4), and may include a strain (tension) mounting (31). Some forms of the assembly may be installed in a live system.

摘要： A power supply system for premises (12') has a meter (20) which stores tariff information (rates and times) received via mains signalling from a controller (13). An outlet (33) has control means (40) responsive to the tariff information stored in the meter. The control means may be programmable simply to allow the outlet to supply power only during low tariff rated periods, or to utilize more elaborate criteria, such as maintaining the supply of power either for a predetermined time regardless of tariff changes once the outlet has been turned on or until the device fed by the outlet has completed its operating cycle (as determined by the current drawn falling to zero), or effecting an inverse control between the tariff rate at which the outlet may be turned on and the time elapsed since it was last turned on.

摘要： A 3-phase overhead distribution network operates at intermediate voltage (e.g. 11 kV to 33 kV), between a high voltage supply network (at e.g. 110 kV or 275 kV) and a consumer mains system (at e.g. 110 V or 230 V). A signalling system uses signals at frequencies preferably in the region of 10 kHz to 100 kHz for signalling over the network, the signals being coupled inductively to and from the network. The signals are coupled to different phases at different points in the network cross-coupling between the phases ensures that signals coupled onto the system on one phase give adequate signal strength for detection at other points in the system regardless of which phase the detector is coupled to.

摘要： A remote electricity metering system is known in which a central station (LC) communicates with meters (U1-U13) over the mains (10-14), with messages to remote meters being relayed by intermediate meters and the route of a message being determined by the central station. The present system provides alarm signalling whereby the meters can communicate direct with the central station. Each meter can generate a respective combination of alarm frequencies, preferably sequentially and inside the frequency band used for normal messaging, and the local controller monitors the mains for those frequencies. An error detecting and/or correcting code can be used for the alarm frequency combinations. The central stationpolls the meter or meters sending the alarm. The meters are microprocessor-based, with the normal message signals and the alarm frequencies being synthesized from a sequence of digital values by a D/A converter.

摘要： A remote metering system comprises a multi-phase mains supply system (10) having a control unit (CS) and a plurality of single-phase consumer meter units (M1-M3) with messages passing between the meter units and the control unit. For phase determination, the control unit and each meter unit includes synchronizing means (CTR1) for synchronizing its message processing to its phase of the mains supply (or one particular phase, for the control unit). The relative phases of the control unit and a meter unit can then be determined, by a comparator (17), from the timing of a message passing between them relative to the phases to which those units are synchronized.

摘要： A remote mains meter reading system comprises a mains system (10, 11, 13, 14), a central station (LC), and a plurality of meters (U1-U11) communicating with the central station by means of messages passed over the mains system. All of the meters act also as message forwarding (relay) units, but knowledge of the topology of the system (i.e. which meters can communicate with which) is known only to the central station. All messages are sent out by, and return to, the central station, the message format includes a list of meters through which the message is to pass. The central station can send out a variety of enquiry (SEARCH) messages to determine the system topology, assign labels to meters, etc. If the mains system includes link boxes coupling different areas together, these boxes preferably filter out messages and includes link units which controllably couple the different areas together.

The present central station includes routing means which comprise, for each meter: a single route table (45-1) which contains a plurality of possible routes (46-1, etc) to the meter; route selector means (47) for selecting among those routes; and means (48, 49), operative if none of the routes in the table enable the meter to be reached, for generating a fresh route and inserting it in the table by displacing a single route from the table. A figure of merit may be stored (at 51) for each route, dependent on the quality of that route or simply on its length. Counters count (48) the number of successive failures of a route and (49) the number of successive failures of successive routes. Routes may be selected in dependence on the time and/or conditions in the mains system.
