Abstract: A sensing device for monitoring an electrical component or apparatus is described. The sensing device is attachable to an electrical conductor and includes a sensor for measuring at least one physical property, a wireless communication unit for transmitting measurement data to a receiver, an energy harvesting unit configured to harvest energy from a current flowing through the electrical conductor and comprising an electromagnetic coil wound around a core, and a connection mechanism to make the core connectable to a strap comprising a material having a high magnetic permeability. The sensing device is configured to be operable when no strap is connected to the core and energy is harvested via an open magnetic circuit as well as when a strap is connected to the core and energy is harvested via a closed magnetic circuit.

Abstract: A fault detection system and method includes a sensor; a processing unit; and an output unit. The sensor is configured to acquire temperature data at a sensor location of a device, wherein the temperature data comprises first temperature data and second temperature data acquired a first time period after the first temperature data. The processing unit determines a temperature magnitude comprising utilization of the first temperature data and/or the second temperature data, and determines a rate of change of temperature. The processing unit predicts a temperature at a location of the device using the temperature magnitude, the rate of change of temperature, and a correlation, wherein the correlation is a correlation of a plurality of temperature magnitudes and a plurality of rate of change of temperatures at the sensor location with a plurality of hotspot temperatures at the location.
