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: The present disclosure relates to an electric motor having a motor terminal box and a diagnostics-signaling unit, which is at least partly located within the motor terminal box. The diagnostics-signaling unit comprises a diagnostics device and an optical output unit. The diagnostics device that is configured to determine an operating condition of the electric motor and to provide an optical-output control signal indicative of the operating condition. Furthermore, the optical output unit that receives the optical-output control signal and that is configured to provide an optical output signal according to the optical-output control signal.
