Abstract:
In a method for detecting the position of at least one switching device in an encapsulated switching installation, the improvement which comprises:a) transmitting a first radio signal, based on a first switch position of the switching device, into the interior of the encapsulation with a radio antenna;b) reflecting the first signal from the interior and from the switching device and producing a first resultant reflection signal symbolizing an image of the interior;c) receiving the first resultant reflection signal with the radio antenna and then storing the first resultant reflection signal;d) transmitting a second radio signal into the interior of the encapsulation, and receiving and storing a second resultant reflection signal; ande) producing a message signal for a new switch position of the switching device in the event of a discrepancy between the two reflection signals.
