To test the tripping time or the tripping current of a Eathr Leakage
Circuit Breaker, make sure to connect the earth wire.
This instrument represents the quickest and easiest way for
servicing, repairing and electrical maintenance of 3 phase system
with earth leakage.
With this equipment, you can, before connecting Load to Supply:
On the supply side; Quickly verify the presence of the three Phases
on a 3 Phases Power System. Confirm the Phase Rotation on a
Powered 3 Phase System. Test the Tripping (disconnection) current
and time of the protections.
5. Brief Product Description
This 3 Phases Rotation and Earth Leakage Tester has 4 test leads
which connects to the 4 mm female sockets on the tester.
These Test leads are color coded.
R(L1) =
Red which connects to R on the tester.
S(L2) =
White which connects to S on the tester.
T(L3) =
Blue which connects to T on the tester.
T(L3) =
Blue which connects to T on the tester.
Earth =
Green which connects to Earth on the tester.
On the other side of the test leads are the probes, also color coded.
The Phase Presence Indicator
has three neon lamps which are the
Phase Presence indicators;
Neon Lamp for Individual Phase Presence Indication = R(L1)
Neon Lamp for Individual Phase Presence Indication = S(L2)
Neon Lamp for Individual Phase Presence Indication = T(L3)
Please note that any of these Neon lamp will only start to light up if
more than 100Vac is present between any 2 phases.
