A magnetic adhesive force monitoring system, magnetic wheeled robot and related method are disclosed. The system includes a magnetic field sensor measuring a stray field portion of a total magnetic field emitted by a magnetic wheel that is magnetically adhered to a ferromagnetic structure, the stray field portion including a portion of the total magnetic field redirected by the ferromagnetic structure. A controller determines a change in a magnetic adhesion force of the magnetic wheel to the ferromagnetic structure based on a change in the measured stray field portion of the total magnetic field. Embodiments also provide for determination of a contact point of the wheel with a ferromagnetic structure.

An exemplary high-current switching arrangement in a generator duct arranged between a generator and a transformer is disclosed. This arrangement includes a pole frame which can be positioned on a base surface, a breaker pole of a generator circuit-breaker which is secured to the pole frame, and a drive which is secured to the pole frame. The breaker pole includes an active component arranged along an axis designed for the conduction and interruption of high currents and which incorporates a power switching point, with two axially spaced current terminals. The drive is arranged on a first of two end faces of the pole frame, and includes a linkage mechanism that transmits power from the drive to the power switching point.
