Devices, systems, and methods for measurement of parameters of electric power transmission lines can improve electric power usage, while wireless circuitry can provide communication from field-located devices. Connection to draw electrical power from the transmission line can be distinct from connection to sense line parameters.

On-line power measurement

The present application is directed to an electrical system including a housing configured to hold electrical components within an internal volume. In one aspect the electrical system is a power transformer. A sensor is mounted to the housing and is configured to sense a parameter associated with one or more electrical components during operation of the electrical system. A control system including a communication unit and a data processing unit is operable for analyzing the sensed parameter and comparing the sensed parameter to a predetermined minimum or maximum threshold value.

Systems, methods, techniques and apparatuses of power network control are disclosed. One exemplary embodiment is a power network comprising a plurality of zones each including a plurality of measurement devices structured to measure electrical characteristics of the corresponding zone, a zone controller structured to receive measurements from the plurality of measurement devices, a distributed energy resource (DER), and a load. Each zone controller is structured to receive a set of local measurements from the plurality of measurement devices of the corresponding zone, calculate a sensitivity matrix using the received set of local measurements, determine whether a voltage violation has occurred in the corresponding zone, determine a DER set point using the received set of local measurements in response to determining the voltage violation has occurred in the corresponding zone, and transmit the DER set point to the DER.

An intelligent fuse provides the operational status of the power network upon which the fuse is installed to a mobile device of a remote user. A fuse electronic circuit embedded in the fuse holder of the fuse captures the characteristic values of the power network and transmits the data to the mobile device. The mobile device has an application installed thereon to calculate the distance to fault location from the recording fuse using the fuse electronic circuit-captured data. The fuse electronic circuit-captured data is further used to visualize the data collected at the measurement points of the electrical system upon which the fuse is installed.

A hardened inductive device and systems and methods for protecting the inductive device from impact is provided. The inductive device is hardened with protective coating and/or an armor steel housing. The hardened inductive device is protected from impact by an object such as a bullet and leakage of dielectric fluid is prevented. Acoustic and vibration sensors are provided to detect the presence and impact, respectively, of an object in relation to the inductive device housing. The measurements of the acoustic and vibration sensors are compared to thresholds for sending alarms to the network control center and initiating shut-down and other sequences to protect the active part. The acoustic sensor results are utilized to determine the location of origin of the projectile.

The sensor data may include temperature data, humidity data, or other environmental data, and may be received by the mobile computing device from one or more external sensors. The building automation application server receives the individualized sensor data from the mobile computing devices and generates a building system configuration based on the individualized sensor data. The building automation application server may optimize the building system configuration for cost, efficiency, or user comfort based on the individualized sensor data. The mobile computing devices and the building automation application server may communicate via one or more collection servers. Other embodiments are described and claimed.
