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.

Electrical power cable monitoring device including partial discharge sensor

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.

Support structure for cable and cable accessory condition monitoring devices

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.
