    摘要： A sensor apparatus for measuring power parameters on a power conductor, such as a high voltage transmission line may include a corona structure, an electronics assembly and a conductor mountable device. The corona structure may define an outer boundary surrounding the electronics assembly and the conductor mountable device. The corona structure may shield the electronic assembly and conductor mountable device from a corona produceable with the power conductor. The conductor mountable device may be a power parameter measurement device, such as a current sensor assembly. The current sensor assembly may be a split-core design that includes multiple transformer cores. The electronics assembly and the conductor mountable device may powered from a line voltage suppliable on the power conductor. Data may be wirelessly transmitted and received with the sensor apparatus.

    摘要： A shield that protects high-value input resistors in a power meter against unwanted effects due to electromagnetic interference from a nearby power supply and/or due to crosstalk from adjacent phases. The shield includes multiple printed circuit board shields that are arranged between each of the input resistors on a main printed circuit board in the power meter. Each PCB shield has a conductive layer that provides the shielding against unwanted energy. The resistors are arranged in a diagonal or parallel manner between each pair of PCB shields to prevent the resistor from movement, which prevents pin fatigue and fixes the value of the parasitic capacitance that is produced in the resistor-PCB-shield combination. In another configuration, the PCB shield is made of a flexible material, and snakes between and over the top or around the side ends of each resistor in a serpentine fashion, protecting the resistors from unwanted energies from both the top and the sides. The PCB shields disclosed herein eliminate variations in the percent error of the measurement phases, which contributes to achieving a highly accurate meter with an overall accuracy of less than 0.1%.

    摘要： An apparatus includes a first jaw (108) coupled to a second jaw (110) to form an opening (114) when the first jaw (108) and the second jaw (110) are closed. An aligning structure couples to at least one of the first jaw (108) and the second jaw (110). A portion of the aligning structure may be disposed within the opening (114) and aligns a power line (128) to a sensor (418) disposed within the first jaw (108) and the second jaw (110).
