Ultimate all-in-one fault locating system 12kV

The P12i is the ultimate all-in-one solution for troubleshooting, relocating
, and pinpointing of cable faults in complex cable networks
up to 15kV. Menu guided computerized operation allows to detect
and precisely locate various faults for even inexperienced users.
Featuring a large color 10,4” screen, the P12i can display measurement
curves, test results and message codes simultaneously. Integrated full-scale TDR capability in combination with the high voltage arc reflection
mode (ARTi) will isolate and pre-locate low as well as high resistance
faults with utmost precision. As a result precise pinpointing will take
much less time. The fast HV surge pulse cycles of 3 sec. with up to 2000
Joule energy supports the most demanding locating jobs while the multidimensional
safety system ensures maximum safety for instrument and
operator. The optional pinpointer Kamphone and Locator S are used for
flash-over faults or cable sheath faults.
