FTB-101 is a eld test box that is intended to be used to verify the leads and the equipment as recommen-
ded by CIGRE and several others.
Connect the “Source”/”Reference” clip to the left-hand side connector and the braid from the clip to the
bottom connector. Connect “Measure” clip to the right-hand side connector and the braid from the clip to
the bottom connector. Also connect the bottom connector to ground/earth (otherwise the system will face
some interference at 50/60 Hz).
If the hook-up and the equipment is in good working order the sweep should look like in the picture below.
The results can be compared with the le “FTB-101.frax” that is shipped with the FRAX software. Available
from the installation folder:
C:\Program Files(x86)\Megger\FRAX\Measurement examples.
More information in Appendix D about connections.
