  • Publication number: 20050288876
    Abstract: 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.

  • Publication number: 20050017751
    Abstract: 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.
