Equipment Testing

                                    Low voltage pulse testing                                                                                ARC multiple pulse testing

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.

This device can use the multiple pulse method to measure distance, and only one short-circuit wire is needed. In addition, when accurately locating the cable fault, it can also be switched to the high-voltage flash-over method (pulse current method - ICE), just remove the short-circuit wire and insert the high-voltage output cable into another HV output port. This ensures high energy output during accurate locating, and will not reduce part of the energy due to the multiple pulse coupler, resulting in less clear sound when listening to the fault discharge sound.
