Function

The STREAMER Pathfinder MK are portable fault indicators. They are intended to be used by the line's operation or maintenance team when a fault appears on the line. The Pathfinder MK helps to locate the faults phase to phase or phase to ground on the line and therefore sensibly reduces the downtimes.

Operation principle

The STREAMER Pathfinder MK Fault Indicators sense out of balance electromagnetic fields in a single or 3-phases medium voltage network. Sensing is triggered when it detects fault current, above the current/time threshold curve, passing in the line conductors. The STREAMER Pathfinder MK will indicate the fault by showing a bright red mechanical flag and/or by sending the information by SMS.

1. Place the Pathfinder MKs at the beginning of each section

2. Close the main breaker and check the Pathfinder MKs to find the faulty section

3. Move the Pathfinder MKs to the faulty section and repeat step 2 in order to isolate the fault accurately
