摘要： A measuring unit for simultaneous measurement of two current values and two voltage values of a power line with three high-voltage conductors includes: three two-pole electrical interconnections, each interconnection being configured to be connected between two separated ends a high-voltage conductors; a first and second current sensor, configured and arranged to measure a current through the first interconnection and through the third interconnection respectively; and a first and second voltage sensor, configured and arranged to measure a voltage between the first and second interconnection and between the second and third interconnection. The measurement of the two current values and the two voltage values is at a floating potential. This measuring unit may be installed directly on all three phases, of a substation for example, with its own internal power source and with no ground connection. Such features are important for power systems with high penetration of variable renewable energy resources such as solar PV or wind.

摘要： Systems and methods for measuring alternating current (AC) voltage of an insulated conductor (e.g., insulated wire) are provided, without requiring a galvanic connection between the conductor and a test electrode or probe. A non-galvanic contact (or “non-contact”) voltage measurement system includes a variable capacitance subsystem which operates to generate a variable capacitive voltage between an insulated conductor under test and earth ground. During measurement, the non-contact voltage measurement system varies the capacitance of the variable capacitance subsystem to change the impedance of a capacitive divider circuit between the insulated conductor under test and earth ground. By sequentially making two (or three) measurements across the variable capacitance subsystem, the AC voltage of the insulated conductor can be determined without requiring any galvanic connection to the insulated conductor. The determined AC voltage of the insulated conductor may then be presented to an operator and/or communicated to an external device.

摘要： An optical sensor assembly that senses current in a secondary electrical cable while sensing voltage in a primary electrical cable. The optical sensor assembly may include a sensor body, a concentrator core for measuring current. The concentrator core may be attached to a first end of the sensor body. The optical sensor assembly may include a plurality of extension arms that extend from the sensor body. The extension arms may include clamping devices on one end that are configured to attach to a first electrical cable. The concentrator core may be configured to at least partially surround a second electrical cable and sense the current from that second electrical cable.

摘要： In order to heighten the level of electrical safety in residential, commercial and industrial networks, stay alert electronic control equipment are needed to detect and report the more common failures in the function of the electric circuitry: high and low line voltage, inversion of the phase sequence in three-phase networks, abnormal current flow between neutral and the ground conductor, and unplanned neutral interruption. When such failures suddenly come about, its effects can provoke harsh damages to users.The integration in a device of the protection action against different failures such as neutral conductor interruption, a very dangerous and unpredictable failure, high and low voltage failures, phase sequence mistakes, and grounding currents in three phase systems, based on microcontrollers technology and the application of a neutral conductor interruption sensor in three phase systems and in any kind two phase systems improves the electrical safety in any electrical system.

摘要： A method for connecting low power radios into a self-assembling and self-healing network with multiple portals to higher speed networks such as, but not limited to, electrical or optical Ethernet is provided for monitoring transmission lines, for example, or other monitoring application. An arrangement of sensors is provided (e.g., sensors can be associated with clamps or positioned along infrastructure being monitored and without dependence on any clamps or other devices) that are designed to communicate and operate in an geographically distributed array to provide increased and autonomous monitoring of large utility, highway, communication and similar networks. A unique collection of sensors (e.g., an anemometer with no moving parts) provides comprehensive diagnostics for improved operation of large geographic scale utility, highway, communication and similar infrastructure.
