TEMPO PE2003 2000H Transmitter PE2003 Pulser Ground Fault Locator

Specifications

Model: PE2003 Pulser
Principle: Earth gradient principle
Power Source: 9-volt battery

Description

The PE2003 Pulser is a Ground Fault Locator based on the earth gradient principle. It accurately locates ground faults in buried wires or cables caused by broken insulation, severed cables, or other faults with ground leakage.

A. Transmitter

The transmitter pulses between the faulted conductor and ground, establishing a DC current flow down the cable to the fault and back through the ground to the transmitter ground stake.

B.Receiver

The receiver indicates the polarity and intensity of minute currents with a center zero meter. It features an on/off sensitivity control and a battery check button for the 9-volt battery.

C. Theory

The receiver A Frame probes the ground along the cable path tomeasure the current flow through the earth. The receiver meter pulses in the direction of the fault, nulling when the fault is located midway between the probes.

Operation

Start at either end of the faulted driver.
Remove power from the conductor and disconnect all loads to prevent damage from high voltage and false readings.

FAQs

Q: How do I know if the instrument is functioning correctly?

A: To check if the instrument is functioning correctly, follow these steps:

Ensure the transmitter and receiver are properly connected.
Check the battery level in the receiver using the battery check button.
Confirm that the receiver meter pulses in the direction of the fault when testing.

DESCRIPTION

The Model PE2003 Ground Fault Locator is based on the earth gradient principle. It will find the precise location of a path to ground fault in any buried wire or cable. Broken insulation, severed cable, and other buried cable faults with ground leakage can be easily and accurately located with the PE2003 Ground Fault Locator.

A. Transmitter
The transmitter voltage is provided by a self-contained rechargeable gel-cell type battery. This voltage is applied to the output leads briefly every few seconds as indicated by the internal beeper, which also indicates the battery condition. Charging the transmitter battery is necessary and advisable for maximum battery life, when the beeper tone becomes weak. Use the AC charger to recharge from a 120 VAC outlet. Overnight charging (12 to 16 hours) is advisable. The Pulser transmitter may also be charged by using the 12 volt automotive system cigarette lighter adapter supplied.
IMPORTANT:The battery is already installed in the 2000H Transmitter but is not connected until the fuse and fuse holder cap are installed. See 5.A. Connecting Transmitter Battery.
B. Receiver
The receiver indicates the polarity and intensity of minute currents with a center zero meter. It has an on/off sensitivity control and a battery check button to examine the condition of the replaceable 9 volt battery.
C. Theory
The transmitter pulses between the faulted conductor and the ground. This establishes a DC current flow down the cable, through the fault to ground, and back through the ground to the transmitter ground stake. The current flow through the earth is measured by probing the ground along the cable path with the receiver “A” Frame. Since the current is directional, the receiver meter pulses or kicks with each transmitter pulse in the direction of the fault.The fault will be located midway between the receiver “A” Frame probes when the receiver meter indication nulls.

OPERATION

Start at either end of the faulted conductor. Remove the power from the conductor under the test and disconnect all loads to prevent damage from high voltage and false readings.
With the transmitter off, connect the clip of the black transmitter lead to the ground stake. Insert the ground stake deeply into the earth. (See Figure 1.)
With the transmitter off, attach the receiver to the “A” Frame and connect the “A” Frame receiver leads to the receiver input jacks – the black lead to the blackjack and the red lead to the red jack. (See Figure 2.)
Turn the transmitter on, and pulses will commence after a short delay at approximately three-second intervals as evidenced by the transmitter beeper.
DANGER – ELECTRIC SHOCK HAZARD
Do not handle transmitter leads, clip, or conductor under test when the transmitter is on. Failure to observe this warning will result in severe injury or death.
Turn the receiver on.Verify the battery condition by pressing the battery \test button and observing the meter. Insert the “A” Frame probes into the\ earth. (See Figure 3.) If all probes are making good ground connection, the receiver will kick toward the the fault (away from the transmitter) in step with the transmitter beeper.
Always adjust the receiver sensitivity for a less than full-scale reading and correlate the transmitter beep with the receiver meter indication.
Move the “A” Frame in line with and down the faulted conductor path. Be sure to insert the “A” Frame probes deeply enough to ensure good ground connection. The strongest indications will be present at the transmitter and at the fault. If the signal begins to fall off or decrease in strength while probing down the faulted conductor path, continue until it comes back up again.
While probing the path, a reversal in the receiver meter, a “black” kick, will be observed when the fault is passed. To determine the exact location, move the “A” Frame in the direction of the black kick until the kick reverses to red. (See Figure 3.) Now move the “A” Frame in small increments back to the red kick until it reverses to a black kick or it nulls. (See Figure 4.)
Note: The receiver will be null when probes evenly straddle the fault. Mark this spot. (See Figure 5.)
Insert the “A” Frame at right angles or perpendicular to the cable path, through the point of the first null. Repeat the procedure outlined in 2.7 until a second null occurs.
Note: The receiver will be null when probes evenly straddle the fault. Mark this spot. (See Figures 4 and 5.)

SPECIAL FAULT LOCATING PROBLEMS

Finding faults under concrete. Dissolve approximately 1/4 cup of salt in one gallon of water and soak two large sponges in the salt water. Wrap the sponges over the end of each probe and attach them with a rubber band. Now proceed as described in 2.7. Re-soak the sponges often and dampen the area where sponges are placed.
Obstructions over the drop. It is not necessary to be directly over the drop path to indicate the fault location. The drop path could be under a street, driveway, or sidewalk. In this case, if the soil parallel to the drop path can be probed (up to 15 feet away), you can locate the fault. Accuracy will not be exact compared to following the path.
Multiple faults. Multiple faults will cause the receiver to reverse at each fault; the most solid fault will produce the strongest signal, kick, or reversal. The best policy is to repair the first fault you locate and then reconnect the Pulser and locate the next one, until you have cleared all the trouble.
High resistance faults. A very high resistance may produce a weak kick. To help make this fault easier to locate, simply turn the sensitivity all the way clockwise. Pouring water on ground stakes will increase sensitivity.
Long distances to the fault. Extreme distances between the transmitter and the fault can cause you to lose signal for a distance between the transmitter and the fault. This is no real problem. Note the distance from the transmitter to the point you lose signal.You will pick the pulse up the same distance from the fault. For example, we will use a distance of 100 feet between the probing. The pulse will be received 100 feet on either side of the fault.

IMPORTANT: The battery is already installed in the 2000H Transmitter but is not connected until the fuse and fuse holder cap are installed.

While holding the fuse holder cap, insert the fuse barrel into the opening on the left side of the transmitter.
Turn the fuse holder cap until secure.
Charge the transmitter battery before storing the unit. Never allow the unit to sit for any length of time with a low or discharged battery.

B. Replacing the Receiver Battery

Remove the two screws on either side of the 2000R Receiver.
Separate the case and replace the 9 volt battery. Observe polarity.
Re-assemble the case and re-install the screws.
Do not overtighten the screws.

C. Cleaning

Periodically wipe with a damp cloth and mild detergent; do not use abrasives or solvents
