provides a non-destructive live test event to identify, locate and validate critical
insulation faults.
The KT1216 (AFDS) uses several Low Energy High Voltage (LEHV) techniques to identify and locate
troublesome intermittent faults in aircraft wiring. This creates an environment conducive to a low energy arc event at the defect
site.*

uses patented DC and AC techniques in concert to effectively screen complete
harnesses.
The arc-event is initiated using a high voltage/energy limited method. The arc event validates the defects
criticality, since the system has now identified a paired fault scenario, where two or more wires have exposed conductors in
close proximity and/or an exposed conductor is in close proximity to a ground plane.

system performance is not compromised by typical impedance variations.





The KT1216 (AFDS) uses several Low Energy High Voltage (LEHV) techniques to induce an arc event at a defect location, to
identify and locate potential defects in aircraft wiring. The energy content is similar to an Electrostatic Discharge (ESD) event.
FAA testing has validated the Non-Destructive nature of the system. Analysis of the traveling waves, resulting from the induced
arc, allows automatic determination of the distance to the defect.
Eliminates unnecessary aircraft down time.

provides the unique capability of finding troublesome
intermit-
tent faults when the aircraft is stationary. The formula is simple: minimum aircraft downtime = maximum revenue. Fault chasing,
via manual inspection or rudimentary tools (i.e. digital multimeter) is very time consuming. Wire testers involving flying leads
(wire-to-wire check) lack robustness, when the task is to identify faulty conductors within a complex harness.

provides the unique capability to identify
and locate troublesome intermittent faults, while the
aircraft is stationary.
The high voltage source allows fault
determination across a small air gap (up to 0.1 inches at sea level).
As is often the case, these types of intermittent shorting conditions
have been nearly impossible to isolate when the aircraft is not
subject to flight loads/vibrations. This has proven problematic for
traditional Time Domain Reflectometry (TDR) methodologies.
* This should not be considered a high-pot test, especially since the A

and the induced arc-event is the feature used to derive distance to fault.

3-D Methodology:
The KT1216 (AFDS) provides distance to fault location,
along the wire run; however, as a practical matter, three
dimensional reference allows a more intuitive location of
the defect site, given the complex spatial environment of
an aircraft.

The optional sequencer, part number 1216305-1, when coupled to an aircraft harness via adapter
cable, allows 40 conductors to be interfaced. This high voltage sequencer has been developed to
provide quick fault screening of the entire bundle, as well as conductor to frame (common faults)
potential faults.
