Portable Pathfinder for ASC earthed networks
The Pathfinder MKVIE is designed to detect faults on networks earthed through an Arc Suppression coil (ASC) or Petersen coil. The ASC triggers automatically during a fault, adjusting reactive and capacitive currents while limiting fault current to small levels to maintain service. Locating faults on such systems is challenging, but the Pathfinder MKVIE analyzes the 3rd Harmonic component and compares vertical and horizontal electromagnetic fields. Changes in the field beyond the fault are detected, and the instrument can be used to patrol overhead lines and pinpoint fault locations based on the point of change in the field.
