Abstract
The arrester comprises a battery of varistors electrically connected between the overhead line and the earth, and a deformable sealed enclosure housing the battery of varistors. The arrester is provided with a fault signalling device for external indication of damage following a short circuit; this device comprises a vertical elastic strap curved around the enclosure and locked on to itself in opposition to its own elastic action, a weakened area in the strap calibrated in such a way as to be broken by the extension of the arrester in case of short-circuit currents due to an internal fault, and a suspension ring for keeping the strap suspended on the arrester after the breaking of the weakened area. <IMAGE>
