    Abstract: Methods and apparatus for electronically displaying metered electrical energy are disclosed. A first processor (14) receives voltage and current signals and determines electrical energy. The first processor (14) generates an energy signal representative of the electrical energy determination. A second processor (16), connected to said first processor, receives the energy signal and generates a display signal representative of electrical energy information. A display (30) is connected to receive the display signal and displays the electrical energy information. In a first embodiment it is preferred for the first processor (14) to determine units of electrical energy from the voltage and current signals and to generate an energy signal representative of the determination of such units and the rate at which the units are determined. In another embodiment the first processor determines and displays watt units, apparent reactive energy units and the rate at which such units are determined. The display (30) may provide energy flow direction information.

    Abstract: A modular closing resistor assembly (20) can be added in line with the interrupter assemblies (16) of an extra high voltage circuit breaker and has a relatively short length. The resistor element consists of two stacks (70, 71) of disks which are disposed side by side and are electrically connected such that the alternate disks (72, 73, 74) of each stack are connected in series with one another. The operating mechanism of the unit includes a linearly moving roller (120) which engages a crank arm (110) which is in turn pivotally connected to operate the movable closing resistor contact (52) with a motion and with a variable mechanical advantage adapted to cause the resistor contacts (52) to close a high speed just after the interrupter contacts close and to open after the interrupter contacts open.

    Abstract: A high voltage open-air switch has a movable disconnect switch blade (120) which contains a circuit interrupter (105) therein having interrupter contacts in series with the open air disconnect switch contacts (145) . The circuit interrupter (105) has a lower BIL rating than the switch. An operating mechanism (117,130) causes the simultaneous independent operation of the interrupter (105) and disconnect switch such that there is a high speed opening of the interrupter contacts, followed by the low speed opening of the disconnect switch contacts (by swinging the blade (120) around the axis of the column 117), and a slow speed closing of the disconnect switch contacts following by the high speed closing of the interrupter contacts. The switch can be adapted to numerous switch configurations and permits substantial savings in space by the reduced mounting requirements for the interrupter assembly.

    Abstract: Système et procédé de communication sur ligne de distribution de courant permettant de réduire les effets d'annulation des signaux à certains endroits de la ligne de distribution (2) à cause d'ondes permanentes causées par les réflexions de signaux porteurs s'appliquant à la ligne de distribution (2). Un seul et même signal de données sortant est modulé sur chacun des divers signaux porteurs (40, 42, 44) ayant des fréquences différentes. Les fréquences des signaux sont choisies de telle sorte que tous les signaux porteurs (40, 42, 44) ne subiront pas une annulation de signal aux mêmes endroits de la ligne de distribution (2). Les signaux porteurs modulés (40, 42, 44) sont appliqués simultanément à la ligne de distribution (2) pour être transmis à des sites éloignés (4), garantissant ainsi une réception du signal de données sortant à chacun de ces sites éloignés (4).
