摘要

A test potential is in each case applied to a number of cables L00...L99 by means of a test distributor, and the other cables are tested for the presence of this test potential. In order to reduce the testing time, each cable is connected to two or more test cables a0, b0...a9, b9 and to an equal number of test cable groups via diodes D0a, Db1 which are connected in the same polarity. A separate test distributor of test distributors PVA, PVB, PVC which become effective successively in time is allocated to each test cable group. IMAGE
