A method for monitoring electrical insulation resistance in an electric system includes: supplying electric power from an external power supply via a first conductor and a second conductor; feeding the electric power to the electric system via a first current collector and a second current collector, each of which are configured to be electrically connected to the electric system via a first main contactor and a second main contactor, respectively; and monitoring the insulation resistance by means of an insulation resistance monitoring unit associated with a control unit and connected to each of the main contactors. The method further includes: maintaining the main contactors in a closed state when the current collectors are disconnected from the conductors, thereby allowing monitoring of the insulation resistance; opening the main contactors and subsequently connecting the current collectors to the conductors; and closing the main contactors thereby allowing monitoring of the insulation resistance. An arrangement for monitoring electrical insulation resistance in an electric system is also provided.

Method and system for monitoring electrical insulation resistance in an electric system

The present invention relates to a model based positioning system that includes a positioning device having at least one transmitter configured to be in a tracking environment, e.g. inserted into a body, a receiver having a plurality of receiver elements arranged outside the tracking environment, a control unit configured to measure amplitude and/or phase information of a signal transmitted from the at least one transmitter and received at each receiving element, and a memory unit for storing a model for each receiving element. The control unit is also configured to estimate the position P of the positioning device by comparing the model for each receiving element with the measured received signal for each receiving element.
