Prelocating methods ARC Multishot: The Arc Reflection Method
overlays and compares a low voltage reference trace and a high
voltage fault trace captured via capacitor discharge through an
inductive (coil-type) filter.
8 comparative measurements per ARM shot are displayed (Multishot
feature), and the results are evaluated automatically. ICE/Surge
Pulse: After fault ignition via capacitor discharge, the Impulse
Current or Surge Pulse method measures the current component of the
travelling wave, This technique is suitable for long cables and
PILC cables.
DECAY: After fault ignition via HV DC source, the DECAY method
measures the voltage component of the travelling wave. This
technique is suitable for very long cables, HV transmission cables
and faults with very high breakdown voltage.
IFL: Intermittent Fault Locating; to find intermittent faults with
temporarily changing characteristics like they often occur in
street lighting systems.
