The invention relates to a fault localizing and identifying device for electric systems. The device comprises a primary unit and a secondary unit. The primary unit comprises at least two connections which are connectible to conductors in the electric system. The secondary unit is connectible to corresponding conductors at a distance from the primary unit. The primary unit further comprises a coupling unit which has a high-impedance and a low-impedance state and which is connected between the connections, and a control unit having an output which is connected to the coupling unit and is adapted to control the coupling unit to shift between the two states. The secondary unit detects the resistance variations. This makes it possible to detect and localize different types of faults. It is also possible to identify or follow a certain conductor. |
