摘要： A high impedance fault isolation system for a radially connected three phase electric power line that utilizes three phase current measurements to determine the presence of a fault without the need for any voltage measurements or a battery powered controller. This eliminates the need for costly phase voltage measuring devices conventionally required to detect high impedance faults, which makes it economical to install fault isolation system at a greater number of locations throughout the power system. The system detects faults using current measurements by computing the negative and zero sequence current components and comparing the amplitudes of the negative and zero sequence components. A fault is detected when the ratio of the amplitudes of the negative and zero sequence components falls within a predefined fault detection range, such as the range from 0.5 to 1.5.

摘要： A limited flash-over electric power switch uses a dielectric gas regulator and a flash-over arrestor to greatly diminish the occurrences of high voltage flash-over during operation of a circuit interrupter. The dielectric gas regulator prevents the flow of the dielectric gas into the arc gap during an initial portion of the opening stroke of the interrupter contacts. Once the arc gap is sufficiently wide to greatly diminish the likelihood of a high voltage flash-over, the dielectric gas regulator allows the dielectric gas to flow into the arc gap to extinguish the arc. The flash-over arrestor snubs out incipient flash-over that may occur as the arc attempts to reform across the arc gap. The flash-over arrestor may be a conductive ring located on the interior surface of the nozzle in the region of the orifice.

摘要： A current monitoring device (CMD) with a set of electromagnetic field sensors located within one or more grounded housings positioned within the combined electromagnetic fields generated by one or more electric power lines. The CMD includes electronics, typically located within the grounded housings, defining impedance networks that combine the measurements received from the field sensors to create output signal indicative of electric current values for the phase conductors. The housings can be conveniently attached and to transmission line towers, distribution line poles, and high voltage power line supports in transmission and distribution substations. The CMD controls response equipment, such as a circuit interrupter that responds to current disturbances detected by the CMD. The CMD may also include communication for sending the current values to a remote controller, such as a central control station, that implements a wide range of response equipment.

摘要： A VAR generator compensation system wherein the voltage of the capacitor or reactor bank is changed as a means of adjusting the phase angle is taught. Briefly stated a reactive bank such as a capacitor bank is connected to the secondary of an autotransformer such that the voltage of the reactive bank is controlled by the autotransformer. The line and load are connected to the primary of the autotransformer, such that changing the voltage of the autotransformer and hence the secondary voltage connected to the reactive bank, thus changes the VARS generated on the grid or system.

摘要： An electric power switch suitable as a capacitor, line and load switch for transmission and distribution voltages includes an external actuator controlled by current transformers (CTs) mounted on live tanks comprising insulators forming dielectric containers that house the contactors of the switch. The CTs are located on the outside of the insulators in the regions of the insulators overlying the internal contactors between the upper and lower high voltage line taps. The actuator and controller may also be located outside the dielectric container, as desired. This configuration minimizes the size of the dielectric container and removes the severe size constraint inherent in design conventional “live tank” switch designs, while also avoiding the need for separate line-mounted CTs. This design also avoids the need for a separate grounded “dead tank” to house the CTs, which are more conveniently located in the outside of the insulators.

摘要： A directional fault location and isolation system for a three phase electric power circuit that identifies a faulted segment by determining the direction of the fault at multiple tap points in the electric power circuit. The directional fault controller, which may be a centralized controller or a number of peer-to-peer controllers located at the tap points, includes communication equipment for exchanging information with the monitoring equipment and the sectionalizing equipment at each sectionalizing control point, which includes the tap points and may also include the substations. The controller also includes processing equipment that determines the directionality of a fault on the power line at each current monitoring device, identifies a faulted line section by identifying a change in the directionality of the fault associated with the faulted line section, and operates one or more of the sectionalizing switches to isolate the faulted line section from the circuit.

摘要： A voltage sag and over-voltage compensation device for an AC electric power distribution system employing cascaded switching devices and a pulse-width modulated transformer. Each stage of the cascaded switching device includes a switching element located within a full-bridge rectifier circuit to allow bi-directional switching through each switching element (i.e., switching through the same switching element during the positive and negative portions of the AC voltage cycle). Each full-bridge rectifier also includes a snubber circuit connected in parallel with a corresponding switching element to absorb the current discharge caused by switching the input power supply to the transformer through the corresponding switching device under non-zero current conditions. On the output side, the voltage sag and over-voltage compensation device includes a filter capacitor to smooth the voltage-corrected AC power supply toward a sinusoidal power supply at the system frequency, and a notch filter to remove noise created by the switching elements.

摘要： An actuator mechanism that decreases the time needed to move the contacts of a circuit interrupter between a closed circuit position and an open circuit position to reduce the probability of the occurrence of restrikes. The actuator mechanism uses a toggle spring arrangement that uses a single spring to move the interrupter through both an opening stroke and a closing stroke. The interrupter is designed to connect to the circuit in parallel, so that the interrupter is not normally in the circuit when the circuit is closed. Because the interrupter is not normally in the circuit, it can be manufactured to less stringent standards than those that apply to electrical components that normally remain in the circuit. The interrupter is well adapted for use as a puffer-type interrupter in which the contacts of the interrupter are contained in an arc-extinguishing gas, such as sulphur-hexaflouride (SF6) gas to further reduce the probability of restrikes and to minimize the effect of occurring restrikes. The interrupter has a bellows arrangement that provides a seal to contain the sulphur-hexaflouride (SF6) gas while allowing the actuator mechanism to freely operate without deterioration of interrupter components. The bellows arrangement enables the interrupter to be utilized in capacitor switching applications in which frequent switching is required. The interrupter may also include a voltage-clamping device connected in parallel across the contacts of the circuit interrupter.
