Description
The RIDGID®A-Frame Fault Locator is a highly
sensitive transmitter and receiver specifically
designed to detect the location of a path to
ground fault (Direct Fault Finding (DFF)) in
the insulation of a buried conductor (such as a
wire or cable). Damaged insulation, severed
conductor, and other faults with ground leakage are easily and precisely located.
Model FT-103 Transmitter connects to the insulated conductor and establishes a current flow,
the current leaks to ground through the insulation fault and back to the ground stake. Model
FR-30 Receiver detects the current flow to
ground through the insulation fault. The receiver provides audio and visual indications of
both signal strength and direction to assist in
detecting and locating the fault. For the AFrame fault detector to work, the conductor
must be in contact with the earth – it will not
work with conductors in conduit.
Additionally, the transmitter can be used to
apply a signal to the conductor for path locating with other receivers, such as RIDGID
SeekTech
done by direct connect and inductive methods.
Multiple frequencies and power levels are provided.

Model FT-103 Transmitter and Model FR-30
Receiver are used for fault locating of conductors through direct connect method.
The Model FT-103 Transmitter only can be
used for path locating with RIDGID SeekTech
and NaviTrack®Locators. This can be done by
direct connect and inductive methods.
1. Confirm have appropriate work area (See
General Safety Rules). Operate in clear,
level, stable, dry location.Do not use transmitter while standing in water.
2. Determine the correct equipment for the
application, see Description and Specifi -
cations sections.
3. Make sure all equipment has been inspected and set up as directed in their instructions.
Fault Locating
It is good practice to locate the conductor path
before attempting to fault locate. This can be
done using a variety of RIDGID locating equipment. If during the location of the conductor
path an unusual amount of signal loss occurs,
this may give some indication of the conductor
insulation fault location. Additionally, use visual
cues and past history to aid in identifying the
conductor path and potential fault locations.
Once the conductor path is determined, the
RIDGID FT-103 Transmitter and FR-30 A-Frame
Receiver can be used to locate ground faults in
the insulated conductor. The Model FT-103
Transmitter connects to the insulated conductor
and establishes a current flow, the current
leaks to ground through the insulation fault
and back to the ground stake. The Model FR-30
Receiver detects the current flow to ground
hrough the insulation fault. For the A-Frame
t
fault detector to work, the conductor must be in
contact with the earth – it will not work with conductors in conduit. Generally, the A-Frame Fault
Locator works best in earth. Use with gravel,
asphalt, concrete or other ground covers may
not work as well.
The signal strength at the fault depends on
the amount of current leaking there. The greater
the leakage, the greater the signal strength.
Connecting Transmitter
1. Disconnect all loads and grounds from
the conductor to be tested and all neighboring conductors to prevent damage from
high voltage and false reading. Both ends
should be known and disconnected. Dis connecting both ends of the conductor
forces all of the transmitter signal through
the fault, improving the fault locate.
2. Insert supplied ground stake into the earth.
®
Ideally, the ground stake should be in line
with the conductor, 3' to 6' (1m to 2m)
from the end. If conditions require, the
ground stake can be placed to the side of
the conductor. Do not to place the ground
stake over the conductor. It is not recommended to use other existing grounds,
existing grounds may result in signal being
inadvertently applied to non-target cables.
A good ground results in a stronger tracing
signal. To get a good ground, insert the
ground stake as far as possible into the
earth. Moist earth will give a better ground
than dry earth. Wetting the earth around
the ground stake can improve grounding.
This lowers the resistance of the circuit.
While moist earth around the ground stake
improves the circuit, do not use the transmitter in areas that are wet, this can increase the risk of electrical shock.
3. Make sure that the transmitter is OFF.
4. Connect BLACK test lead to the ground
stake. Always connect to the ground stake
first.
5. Connect the BLACK and RED test leads
to the Transmitter.
6. Connect the RED test lead to the conductor to be tested (see Figure 9).

2. When fault locating, generally the receiver
should be used over the conductor, with
the front receiver spike towards the expected fault and the rear receiver spike towards the ground stake. The receiver
spikes should evenly penetrate the earth
to make good electrical contact. The current flowing in and out of the ground
spikes supplies the signal to locate the insulation fault (see Figure 10).
Figure 9 – Transmitter Screen
Adjust the signal power by pressing the signal
power button to cycle through the settings (low,
medium and high). Using high power may result in signal going to ground at non-target
points, low power may mean a circuit is not created. The transmitter will display circuit resistance (OHMS) at the bottom of the LCD. The
lower the resistance the better the locate signal.
To improve the circuit, improve the ground,
check the lead connections or increase the
power.
The transmitter will continuously beep when
there is a circuit. The lower the circuit resistance, the quicker the beep. The transmitter
will beep three times and a pause (repeating) if there is no circuit.
If the transmitter display shows voltage warning (Figure 3), the transmitter is connected to
live voltage. If this happens, DO NOT TOUCH

highest near the ground stake and at
faults. Press the “Ref” button to store a reference signal strength near the ground

The receiver display arrows will indicate
the direction of the fault. Fault direction is
also indicated audibly - a long slow beep
indicates forward direction and a quick
beep indicates backward direction.

4. Remove the receiver from the earth and
move several steps as indicated by the
irectional arrow and beeping along the
d
conductor path. Reinsert the receiver
spikes into the earth (Figure 11).
Continue moving away from the ground
stake along the conductor path. Signal
strength should drop (in some cases going
to zero) and then rise as you move towards a fault.
5. Signal strength will peak over the fault. If
you pass the fault, the directional arrow will
change direction and the beep will change
from long slow to quick beep and the signal strength will decrease. Continue to
move the receiver back and forth until
slight movement causes the directional
arrows and beeping to toggle back and
forth. At this point, the fault is centered between the spikes of the receiver.
Compare the signal strength to the reference signal strength taken near the
ground stake. They should be similar. If the
fault signal strength is much lower than the
reference value, you may not have located a fault. For instance, a grounded
splice point would behave as a fault during
the locate, but would give a much lower
signal strength. For a low fault signal
strength, you may want to mark the location and continue down the conductor
ath looking for a fault signal strength
p
closer to the reference signal.
Once a fault is located with a signal similar
to the reference signal, turn the A-Frame
Locator perpendicular to the path of the
conductor. Move the receiver back and
forth until slight movement causes the directional arrows and beeping to toggle
back and forth. At this point, the fault is
centered between the spikes of the receiver. See Figure 12. Mark the location of
the fault.
6. Once the locating is completed, press the
ON/OFF button to turn the transmitter OFF.
Always turn the unit OFF before disconnecting the cable leads to reduce the risk
of electrical shock. Remove the cable lead
from the target conductor first. Always disconnect the cable lead from the target
conductor first before removing the cable
lead from the ground spike to reduce the
risk of electrical shock. Disconnect the
cable lead from the ground spike.
Locating Below Paved
Surfaces
Locating can be difficult if the fault is below a
paved surface, because the receiver spikes
cannot make good electrical contact with
the earth. In this case, there are several
methods that can be used.

If the paved area is relatively small, the
•
receiver can be used around the periphery
of the area. The receiver can be rotated
side to side, and where the receiver directional arrows and beeping toggle back
and forth, extend a straight line perpendicular to the center of the A-Frame Receiver.
Do this in several locations around the
suspected fault area. The straight lines
should all intersect at the same point. This
is the location of the fault. This method of
locating is less exact than placing the receiver directly over the conductor. See
Figure 13.
• An alternate way to locate below paved
surfaces is to improve the conductivity between the pavement and the receiver with
water. One method is to attach sponges to
the spikes of the receiver. Wet the sponges
with water and keep wet. Conduct the fault
locate normally.
• Another method is to wet the surface of the
pavement with water and conduct the fault
locate normally. Do not do this in the area
of the transmitter – this increases the risk of
electrical shock.

Figure 13 – Locating below paved surfaces
Multiple Faults
If there are multiple faults in the conductor,
the faults will have signals proportional to
the amount of current leaking. The locate is
done the same as for a single fault, but the
signal strength will not be as strong. Typically,
the largest fault (least resistance fault) is
easiest to find. Best practice is to find and repair the first fault and continue the locate
for other faults.
Path Locating
The FT-103 Transmitter can be used with other
commercially available receivers (such as the
RIDGID SeekTech or NaviTrack receivers) to
path locate conductors. The FT-103 transmitter
A-Frame Fault Locator
an be used to apply an active tracing signal to
c
a conductor in three ways:
• Direct Connect – The transmitter’s leads
are connected directly to the target conductor and a suitable ground. This method is
most commonly used when the target utility is accessible. Direct connect should not
be used for energized (live) conductors.
• Inductive Clamp (optional equipment) –
the jaws of the inductive clamp encircle
the target conductor; if the conductor is insulated, there is no metal to metal contact.
This method is commonly used when the
target utility is accessible but direct connect is not possible on an insulated cable.
• Broadcast Inductive Mode – The transmitter generates a field, which in turn induces
a current in the target conductor. There is no
direct connection between the transmitter
and the target conductor. The transmitter is
placed over and inline with the target conductor. The transmitter’s internal antenna induces a signal onto the target conductor.
This method is most commonly used when
the target utility is not accessible.
Disconnect all loads from the conductor to
be tested and all neighboring conductors to
prevent damage from high voltage and false
reading.
Direct Connect Path Locating
Method
1. Insert supplied ground stake into the
earth. Or, if other good grounds are available in the area, they can be used.
A good ground results in a stronger tracing
signal. To get a good ground, insert the
ground stake as far as possible into the
earth. Moist earth will give a better ground
than dry earth. Wetting the earth around
the ground stake can improve grounding.
This lowers the resistance of the circuit.
While moist earth around the ground
stake improves the circuit, do not use the
transmitter in areas that are wet, this can
increase the risk of electrical shock.
The far end of the conductor should be
grounded.
2. Make sure that the transmitter is OFF.
3. Connect BLACK test lead to the ground
stake. Always connect to the ground stake
first.
4. Connect the BLACK and RED test leads
to the Transmitter.

6. Press the ON/OFF button to turn the transmitter ON. When the transmitter is turned
on, it is set to the last used frequency.
Press the frequency selection button to
cycle through frequency settings to the
desired locating frequency.
Adjust the signal power by pressing the
signal power button to cycle through the
settings (low, medium and high). Using
high power can couple into non-target
conductors, low power may mean a circuit
is not created. The transmitter will display
circuit resistance (OHMS) at the bottom of
the LCD. The lower the resistance the better the locate signal. To improve the circuit,
improve the ground, check the lead connections, increase power or change the
frequency.
If the transmitter display shows voltage
warning (Figure 3), the transmitter is con-
nected to live voltage. If this happens,
DO NOT TOUCH THE TRANSMITTER,
LEADS OR CONNECTIONS. The tar-
get conductor is energized and there is
the risk of electrical shock. Use high voltage precautions to disconnect.
7. Check the circuit and adjust signal power,
grounding or connections to ensure locatable field.
8. Turn ON the receiver/locator and follow
the instructions for the receiver. Make sure
the receiver’s frequency is set to match that
on the transmitter. Confirm the receiver is
picking up the transmitted frequency by
holding it near the transmitter and observing the increase in receiver signal.
9. Once the locating is completed, press the
ON/OFF button to turn the transmitter
OFF. Always turn the unit OFF before disconnecting the cable leads to reduce the
risk of electrical shock. Remove the cable
lead from the target conductor first. Always
disconnect the cable lead from the target
conductor first before removing the cable
lead from the ground spike to reduce the
risk of electrical shock. Disconnect the
cable lead from the ground spike.

clamp.
2. Insert the plug of the inductive clamp
into transmitter (see Figure 2).
3. Clamp the jaws of the inductive clamp
around the target conductor. Make sure
that the jaws of the clamp are fully closed.
(See Figure 14). Both ends of the conductor should be grounded for best results.

Conductor
4. Press the ON/OFF button to turn the trans mitter ON. When the clamp is plugged in
the clamp symbol ( ) shows on the
screen and only clamp frequencies are
available. Press the frequency selection
button to cycle through frequency settings
to the desired locating frequency. Adjust
the signal power by pressing the signal
power button to cycle through the settings
(low, medium and high). The inductive
clamp typically works best with frequencies around 8kHz, 33 kHz, 93kHz.
5. Check the circuit and adjust signal strength
(see Figure 3, Circuit Information).
6. Turn ON the receiver/locator and follow
the instructions for the receiver. Make
sure the receiver’s frequency is set to
match that on the transmitter. Confirm
the receiver is picking up the transmitted
frequency by holding it near the transmitter and observing the increase in receiver signal.
7. Once the locating is completed, press
the ON/OFF button to turn the transmitter
OFF.

the receiver at least 30 feet from the transmitter to prevent this. (See Figure 16).
One way to confirm that you are tracing the
target conductor and not the transmitter
field is to look for a strong, stable prox imity
signal and a valid depth measurement on
the receiver. While directly over the energized line you can also raise the receiver a
set distance off of the ground, and verify
that the depth reading on the display e quals the distance that you raised the receiver.
