摘要： A high voltage capacitor includes multiple capacitor packs housed in a canister. A capacitor pack status monitor includes a current sensor measuring an electric current through an associated capacitor pack and a radio transmitting a first signal representative of the electric current through a selected capacitor pack. The monitor also includes a voltage sensor measuring an electric voltage across the associated capacitor pack and a radio transmitting a second signal representative of the electric voltage across the selected capacitor pack. Electronics compute an impedance associated with each capacitor pack. Each current sensor may include a current transformer positioned around a main power line energizing a respective capacitor pack. Each voltage sensor may include a relatively large high voltage discharge resistor connected across the respective capacitor pack, and a relatively small voltage measurement resistor connected in series with the relatively large high voltage discharge resistor across the respective capacitor pack.

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： Embodiments of the present invention include a test-boost electric power recloser that limits the duration of the test current imposed on the power line to less than two electric power cycles, and preferably less than one electric power cycle, when attempting to reclose into a fault. The test-boost recloser sends a test pulse causing a non-latching close followed by a boost pulse causing a latching close if waveform analysis based on the test close indicates that the fault has likely cleared. The test-boost approach can typically be implemented through a software and calibration upgrade to a conventional single-coil recloser, accomplishing results comparable to a dual-actuator recloser at a much lower cost. The recloser may perform iterative and feedback learning feedback processes to automatically improve its operation over time in response to measured fault and non-fault conditions and its success in predicting whether faults have cleared.

摘要： A system or method for monitoring an electric power lightning arrester including an arrester current sensor providing an arrester current measurement, and an arrester voltage sensor providing an arrester voltage measurement. The system detects a switching signature based on the arrester current measurement or the arrester voltage measurement distinguished from background noise and lightning signatures and computes a measured arrester impedance based on the arrester current and arrester voltage measurements. The system then compares the measured arrester impedance to a nominal or historical arrester impedance, determines that the arrester is faltering based on the comparison of the measured arrester impedance to the nominal or historical arrester impedance, and places an order for replacement of the arrester based on the determination that the arrester is faltering. The system operator then replaces the arrester during a fair-weather, typically off-peak period to avoid failure of the arrester during a lightning strike.

摘要： A calibration joint for a three-phase electric disconnect switch includes a linkage pipe extending through a lock ring, which includes an axial guide shaft, a threaded shaft, and a self-piercing set screw securing the lock ring to the linkage pipe. The linkage pipe also extends through a clevis housing, which includes an axial joiner shaft and a clevis bracket securing the clevis housing to an operating lever of the disconnect switch. An adjustment rod extending through the axial guide shaft of the lock ring, through the axial joiner shaft of the clevis housing, and engaging with lock nuts allows axial adjustment of the clevis housing with respect to the lock ring, and thus with respect to the linkage pipe. This, in turn, allows fine adjustment of the blade and jaws of an associated phase switch with respect to the switch actuator independent of the other phase switches.

摘要： A smart switch allows distributed generators to “ride through” non-three-phase faults by very quickly detecting a non-three-phase phase fault, locating the fault, identifying the “responsive sectionalizer switches” that will be involved in clearing or isolating the fault, and selecting one of the responsive sectionalizer switches to direct back-feed tie switch operations. The responsive sectionalizer switches trip only the faulted phase(s), and the selected sectionalizer switch instructs a back-feed tie switch to close to back-feed the distributed generators prior to conducting the typical fault response operation. This typically occurs within about three cycles, and is completed before the normal fault clearing and isolation procedures, which momentarily disconnect all three phases to the distributed generators from the normally connected feeder breaker. The looped connection to an alternate feeder breaker during these operations allows the distributed generators to “ride through” the normal fault clearing and isolation procedures.

摘要： A high voltage electric switch includes contacts with graphite carbon electrode forming the arc gap. In addition, the carbon contacts are located in a chamber containing at least 60% carbon dioxide (CO2) as a dielectric gas to achieve improved arc interrupting performance. In conventional switches, the metallic contacts introduce metallic vapors into the arc plasma that inhibits the ability of the dielectric gas to interrupt high voltage, high current arcs. As the element carbon is inherently present in CO2 gas, the addition of vapors from the carbon electrodes into the dielectric gas does not significantly interfere with the dielectric arc-interrupting performance of the CO2 dielectric gas.

摘要： A high voltage capacitor current monitor that attaches to a bushing on the exterior of a capacitor container (commonly referred to as a “can”). The capacitor current monitor, which draws operating power from the power line, detects the current flowing through the high voltage capacitor and can be used as part of a capacitor status monitor to detect internal failures down to the level of a single capacitor pack. The monitor may include a radio transmitter and/or a visual status indicator, such as an electronic flag, indicating the detection of a fault or capacitor failure. The current monitor may also include a power supply current transformer providing power to the monitor from the power line. Capacitor current measurements may be communicated with a remote transmission unit (RTU), which communicates with a central control station that schedules capacitor maintenance based on the data received from the status monitors.
