| LineTroll 3100 |
The LineTroll 3100 is used to locate short-circuit and earth faults in overhead line distribution networks. LineTroll 3100 is a 3-phase unit fully covering the different fault configurations that may occur.
The indicators are placed at strategic locations along the line such as after branching points and sectionalisers. It mounts on the pole, 3-5 meters below the conductors by means of screws or wrapping-bands. Live line mounting is done safely, easily and rapidly.
Upon detecting a fault on the line, the indicator gives off an intermittent LED flashing or an optional Xenon flash. This flash can be seen within 200-300metres distance (for Xenon up to 1,5 km at night) during night. The lens of the indicator can be turned to either side for optimal visibility
LineTroll 3100 provides fast fault location enabling reduction in outage times. This represents enhanced service to the customers thereby improving the utilities image. Another important aspect of using fault indicators is that unnecessary operations of circuit breakers and sectionalisers to locate faults are avoided. This way the indicators help to reduce wear and tear as the reclosing cycles causes stress to the switchgear.
