TDR Device: InterFlex 140
Rugged 3-phase TDR based power cable
faultpre-locator for field measurement
The InterFlex 140 is a high
performance 3-phase Time Domain Reflectometer (TDR) for pre-locating cable
faults primarily in underground power cable networks from low to high
voltage.
The rugged design and a
powerful measurement impulse of 160V make it ideally suited for demanding
field measurement tasks.
Supporting all relevant
TDR-HV modes, the instrument capabilities can be further increased by
combining it with a suitable HV source and coupling filter; As a result, the
precise location of high resistance and intermittent faults is possible.
The bright color 10.4 "
display, minimal controls and an easy to navigate user menu simplify
operation.
Numerous analytical features
(comparison, difference curves etc.) provide powerful support during complex
fault locating situations.
