  Apparat zum Auffinden von elektrischen Potentialunterschieden. 



   Die Neuerung betrifft einen Apparat zum Auffinden von   e ! ektrischen   Potentialunterschieden an der Erdoberfläche, die z.   D.   infolge von Isolationsfehlern an elektrischen Leitungen entstehen, zum Zwecke, deren Lage festzustellen. Sie kommt vor allen Dingen dann zur Anwendung, wenn 
 EMI1.1 
 Auge oder mit Feldstecher sichtbare Zerstörung des Isolators oder seiner Umgebung hervorzurufen. 



   Der Apparat ist in seinen wesentlichen Teilen in der   Zeichnung   abgebildet und besteht aus zwei   Metallsohlen   1 und 2, die durch biegsame   Leitungen.'3 und 1 mit   den beiden an einem

   Kommt er mit dem Gerät in die Nähe stromdurchflossener Stellen im Erdreich, so ertönt das Telephon mehr oder minder deutlich, je nachdem er sich dem   Leck In   der Leitung in der Richtung der Stromlinien nähert oder von ihm entfernt. Die Tonstärke erreicht einen Höchstwert,

   In unmittelbarer   Nähe   der Fehlerstelle kann der Ton sehr stark werden und der Strom die Fernhörer unter   Umständen   zerstören. Um dies zu verhindern, kann man durch den Schalter. 5 die Fernhörer kurzschliessen und das Erdreich ohne Gefahr betreten.

  Apparatus for finding electrical potential differences.



   The innovation concerns a device for finding e! electrical potential differences on the earth's surface, which z. D. arise as a result of insulation faults on electrical lines, for the purpose of determining their location. Above all, it is used when
 EMI1.1
 Visible destruction of the isolator or its surroundings with eye or binoculars.



   The main parts of the apparatus are shown in the drawing and consist of two metal soles 1 and 2, which are connected by flexible lines 3 and 1 to the two on one
 EMI1.2
 



   If he comes with the device in the vicinity of places in the ground through which there is current, the telephone sounds more or less clearly, depending on whether he approaches or moves away from the leak in the line in the direction of the streamlines. The tone level reaches a maximum
 EMI1.3
   falls. axas is therefore capable. determine the direction at the same time. in which the faulty point is to be found.



   In the immediate vicinity of the point of failure, the sound can become very strong and the current can destroy the remote receiver under certain circumstances. To prevent this, you can use the switch. 5 Short-circuit the remote receiver and step into the ground without risk.
