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.
