Abstract
Circuit arrangement for fault locating in conjunction with equipment for the trunk feeding of electrical loads by means of dc series feeding in which the trunk supply circuit is equipped with cross branches conducting only for currents in the direction of a test current. In such a circuit arrangement it is possible to indicate the results of the fault locating in a simple manner. Towards this end, one window discriminator for each load is provided in the supply point. This circuit arrangement can be used advantageously in communications equipment having trunk fed waystations.
