Abstract: Techniques, systems and articles are described for monitoring electrical equipment of a power grid and predicting likelihood failure events of such electrical equipment. In one example, a cable accessory is configured to couple to an electrical power cable and includes a partial discharge sensor and a communications unit. The partial discharge sensor is configured to detect partial discharge events and output data indicative of the partial discharge events. The communications unit is configured to output event data based at least in part on the partial discharge data.

Abstract: In general, a monitoring system includes one or more nodes that are capacitively coupled to a cable of a multiphase electric power line. In some examples, a node includes a coupling layer disposed over a jacket layer of the cable and capacitively coupled to a shield layer of the cable. In some examples, a node may include a first coupling layer capacitively coupled to a first cable, and a second coupling layer capacitively coupled to a second cable, such that the node is differentially coupled to the cable pair to generate a differential data signal and to perform at least one of: sensing a native signal within the cable pair; injecting an intentional signal into the cable pair; receiving an intentional signal from within the cable pair; or providing a channel characterization.

Abstract: A method for regulating input impedance of a switching regulator, the method comprising: obtaining, at an impedance controller: (a) a measured voltage value that is indicative of an input current of the switching regulator and (b) an input voltage of the switching regulator, wherein a ratio of the input voltage to the input current defines an actual input impedance of the switching regulator; generating a control signal by the impedance controller, in accordance with a difference between the actual input impedance of the switching regulator and a desired input impedance of the switching regulator, wherein the desired input impedance is a predefined impedance; and controlling a feedback node feeding the switching regulator, in accordance with the control signal, to realize an output voltage of the switching regulator for achieving the desired input impedance, wherein the feedback node is external to the switching regulator, thereby regulating the input impedance of the switching regulator externally to the switching regulator.

Abstract: Devices are described that support, house, and protect an electrical cable monitoring system that is electrically coupled to an electrical cable. An example support structure includes an elongate body including an interior surface extending along and concentric to an axis of the electrical cable. The body is configured to engage a cable accessory disposed on the electrical cable. The support structure includes a first electrode attached to the interior surface and configured to operatively couple to the cable accessory. The support structure includes a second electrode attached to the body and configured to operatively couple to the shielding layer. The support structure includes a monitoring device attached to the interior surface and operatively coupled to the first and second electrodes. The monitoring device is configured to monitor one or more conditions of the electrical cable or the cable accessory.

Abstract: Techniques, methods, systems and articles are described for monitoring electrical equipment of a power grid, identifying installation and/or configuration errors of such electrical equipment, and automatically correcting the errors. In one example, a system includes at least one processor and a plurality of sensors coupled to a multi-phase power line comprising a plurality of electrical cables that are each associated with a respective phase. The plurality of sensors are configured to generate sensor data that is indicative of one or more conditions of the electrical cables. The at least one processor is configured to receive the sensor data and determine, based at least in part on the sensor data, whether a sensor of the plurality of sensors is installed correctly. The at least one processor is also configured to perform an action in response to determining that the sensor is not installed correctly.
