The apparatus may further comprise a powering current transformer set within the enclosure and operative to receive power from the power line on a primary winding and deliver power on a secondary winding. The apparatus may further comprise power supply circuitry set within the enclosure, the power supply circuitry powered through the secondary winding from the powering current transformer and operative to supply power to the amplifier. The apparatus may further comprise at least one of secondary leads and secondary terminals extending from the enclosure, coupled with the active current transformer and operative to deliver the scaled version of the current outside of the enclosure.

    摘要： Systems and methods for reclassifying instrument transformers. A line mounted device that includes a sensor that can be attached to a power line. The line mounted device generates data or representations of the power parameters of the power line. A processor in the line mounted device produces modified representations of the power parameters that are transmitted wirelessly to a microprocessor based device. The microprocessor based device also receives second representations of the power parameters from legacy instrumentation. Compensation data is produced based on the modified representations from the line mounted device and the second representations from the legacy instrumentation. The compensation data can be used to compensate or correct the representations of the power parameters from the legacy instrumentation even after the line mounted device is no longer attached to the power line.

    摘要： Devices that couple to high voltage transmission lines obtain power themselves using the body capacitance of an element of the devices. The devices generate a comparatively lower voltage from the current flowing between the high voltage line and the element of the device that generates the body capacitance. The devices can be used to operate sensors that monitor the transmission lines or parameters of the power distribution system, such as current, line temperature, vibration, and the like. The devices can also be used as indicators, such as aircraft warning lights, information signs, etc. In addition, the devices can operate as RF transmission/reception or repeater devices, radar devices, mesh networking nodes, video/audio surveillance, sound emitting devices for scaring animals, drones that traverse the power line, etc. Because the devices operate in response to line voltage rather than current, the devices are reliable even in low current conditions.

    摘要： Systems and methods for monitoring power in a conductor. A flex circuit may include multiple layers including a voltage sensing layer, a coil layer, and a ground layer. The coil layer includes traces that form a coil structure around a conductor when the flex circuit is wrapped around the conductor. The coil layer generates a voltage that may be integrated to determine a current in the conductor. When the flex circuit is wrapped around the conductor, the voltage sensing layer is closest to the conductor. The voltage sensing layer forms a capacitor with the conductor. Using an adjustable capacitive voltage divider, the voltage of the conductor may be determined from a voltage signal received from the voltage sensing layer.
