    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.

    摘要: A security system for programmable revenue class electricity meters. Each programmable revenue class electricity meter includes a metering portion or stage that couples to a power line. The metering portion is responsive to and senses the electricity in the power line and provides a digital output. The programmable revenue class electricity meter includes a processor that runs programming that records, calculates, and/or stores data relating to the electricity sensed by the metering portion. In particular, the programming records, calculates, and/or stores revenue-related data that can be used for calculating charges for the electricity. The programming can be changed by authorized persons to modify the types of data that can be measured, calculated, recorded, displayed, communicated, and/or stored for any desired purpose and in particular for revenue-related purposes. Modification of the programming and access to information is limited to authorized persons by means of the security system. The security system includes security system programming in the meter that checks for a code word that is required to be input prior to any changes to the revenue-related programming can be effected. The security system programming compares the input code word to a code word stored in the meter and unlocks restrictions on modification of the revenue-related programming if the input code word matches the stored code word.

    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.
