Function
Streamer’s Pathfinder 360 ALPHA (P360A) is pole mounted fault indicator. It is intended on the distribution lines up to 66 kV. The P360A helps to locate the faults phase to phase or phase to ground on the line with 2 very bright LEDs and therefore sensibly reduces the downtimes.
Operation principle
Streamer’s P360A Fault Indicators sense out of balance electromagnetic fields in a single or 3 phases high voltage network. Sensing is triggered when it detects fault current, above the current/time threshold curve, passing in the line conductors.
Streamer’s P360A will indicate the fault by lighting a bright LED and by sending the information by SMS/data to a cell phone or directly to a server.
