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: A system and method of synchronizing a mesh network comprising a plurality of nodes are provided. The method may include sensing and transmitting, by a first subset of the plurality nodes, temperature values of the first subset nodes; receiving, by at least one back-end unit, from the first subset nodes, the temperature values of the first subset nodes; determining, by the at least one back-end unit, for a second subset of the plurality of nodes including all the first subset nodes, respective ambient-related clock drift values, based on the temperature values of the first subset nodes and an inter-node data; transmitting, by the at least one back-end unit, the respective ambient-related clock drift values to the second subset nodes; and determining, by the second subset nodes, ambient-related time offset values between each respective two nodes of the second subset, based on the respective nodes' ambient-related clock drift values.
