The TEL1 is the Basic Test Equipment an Electrician cannot do without. TEL1 is
a Dual Function Test Instrument utilized to Verify Electrical Wiring
Connections and the Functioning of Earth Leakage / Residual Current Detectors
devices by forcing the ELCB/RCD to trip.
This verifies that the protection device open the mains power supply circuit
when a current higher than a certain amplitude circulate into the ground/earth
wire (generally around 15mA)
This ensure the electrical installation meet safety and regulation
requirements.
The Wiring Check is reported on the Bright Neon Lights and the Key code is
shown on the table located under the tester.
The table tells the user if the wires are connected correctly or not and guide
the user to solve his fault, if any.
However, it does not detect or show if a short circuit is present between the
Neutral and Earth/Ground wires as well as does not detect or show if a swap
occured between the Neutral and Earth/Ground wires due to the fact that these
wires are connected together at the supply transformer or some time, again,
are connected together by a link, somewhere else in the power distribution
system.
WIRING CHECK TABLE
The WIRING INTEGRITY CHECKER of the TEL1 uses three Large and Bright Neon
Lights to detect and display voltage conditions on and between powered
electrical wires.
These neon lights will lit according to a different sequence related to the
wiring conditions of the electrical system. The table located under the tester
shows the wiring conditions.
The Residual Current Detector or Earth Leakage Circuit Breaker Tester injects
and simulate a Ground/Earth Fault current into the Earth/Ground wire to trip
the device under test. The fault current can be increased by rotating the
switch to the new higher value to force the device to trip.
Once selected by the rotary switch, the user press the TEST button to inject
the current. When the current is Flowing into the Earth/Ground wire, the lear,
LED lit, confirming that current is still flowing into the Earth/Ground wire.
Power Resistors are utilized to inject the current and No Phase shift is
introduced between voltage and current. When rotating the selector, different
resistors are selected by the rotary switch, this in turn, change the current
selection. The User need to select the current on the rotary switch and then,
press the TEST button shortly to inject the Fault Current. This ensure the
fault current is only temporary injected into the system.
An Example on How to use the device is as follow:
Rotate the switch anti-clockwise to the lowest current setting. Plug the
tester into the wall socket. The wiring check will now indicate the wiring
condition of the system as seen from the plug. Verify the Neon lights against
the table. If the wiring is correct, carry on with the next test. If the
wiring is not correct, then you need to solve the problem before continuing.
If the wiring is correct, then you are ready to test the ELCB/ RCD
sensitivity. Press TEST for a short time and check the IEARTH LED while
pressing. If the IEARTH and the Neons lights are now OFF, that mean the
ELCB/RCD tripped. If the lights are still ON, then, stop pressing the Test
button and increase the selected fault current and press Test again. IEARTH
LED lit when current is going into the Earth/Ground wire. Most domestic
breakers trips around 15mA of sensitivity.
The TEL1 help the user finding the sensivity at the ELCB/RCD trips.
