Abstract: Techniques, systems and articles are described for preparing electrical cables for connections to a power grid. In one example, a system includes a cable preparation device configured to cut one or more layers of an electrical cable and a computing device configured to control the cable preparation device to cut the one or more layers of the electrical cable. The computing device may determine one or more target cutting distances and determine whether an actual cutting distance satisfies the target cutting distance. The computing device may detect defects in the electrical cable. The computing device may further determine whether the cable preparation device should be serviced.

Abstract: A partial discharge (PD) detection system includes a node including a sensor configured to capacitively couple to a shield layer of a cable of an electric power line. The sensor is configured to collect, from the cable, sensor data indicative of an alternating-current (AC) electrical signal in the cable. The system further includes a high-pass filter configured to filter out low-frequency signals from the sensor data, and processing circuitry configured to detect, based on the filtered sensor data, a PD event at a location on the cable that is local to the sensor.

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: 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.

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 sensing device is configured to couple to an electrical power cable. The sensing device includes a plurality of concentric layers and a monitoring device. The plurality of concentric layers include a first layer, second layer, and third layer. The first layer is configured to concentrically surround a central conductor of the electrical cable and includes an insulating material. The second layer includes a conducting material. The third layer includes a resistive material configured to resist electrical flow between the second layer and a ground conductor exterior to the third layer. The monitoring device includes a sensor and communication unit configured to output data indicative of the sensor data.

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.
