Abstract: A method, device, and system for detecting a current leak in a traction power rail. Magnetic or electrical properties of the rail are measured. The measurements are performed using a rail instrument that senses the properties around the rail at various times while the instrument is being moved down the rail, such as using a cart or train. The rail instrument may be a flux concentrator or open Rogowski coil. The locations of the rail, about which the readings are taken by the rail instrument, may be determined and correlated with the measurements themselves. The method may comprise measuring the magnetic field of the rail along a length of the rail, and identifying a leak based on differences between the magnetic field measurements. The system may comprise a cart comprising the rail instrument and a location instrument.

Abstract: An electronic device, and a magnetic energy harvesting device and method of harvesting magnetic energy, for electric metallurgical furnaces and similar environments. The device comprises a conductor which is configured to become induced with electricity in response to a time-varying magnetic field. The field may be irregular, such as near a metallurgical furnace or a similar environment. The electronic device may be a transmitter in a metallurgical electric furnace. The transmitter may be connected to an environment sensor. The electronic device may be powered by the magnetic energy harvesting device. The magnetic energy harvesting device may a wire loop or a coil. The method comprises inductively harvesting energy from magnetic field fluctuations caused by a metallurgical furnace or a similar environment to wirelessly power the electronic device.
