The Leakage Test is an alternate method to perform insulation resistance tests. Leakage testing is a major
function of the TNT - Series
Please Note:
A
Visual Inspection
test must be carried out before any others (refer to
First
Test
Section)
This test determines errors of leakage not otherwise detected in a normal insulation test. If there are any doubts
with insulation testing of the equipment, the Standard
(AS/NZS 3760 since 2001)
allows for a
leakage
test
to be
carried out
instead.
The TNT - Series appliance testers have been designed to perform these tests. The
Leakage
Test
applies power to the Device Under Test and measures any imbalance or leakage current. The leakage is
tested to the limits of the class types specified in the Standard AS/NZS 3760 i.e. Class 1 = > 5mA as
Fai
l
& Class
2 = > 1mA as
fail.
The Limit of imbalance measured on the TnT-RCD, + appliance tester will read well in excess of the limits set in
mA. However, should the supply circuit be protected by an RCD this device will trip anywhere between 10 to 30mA
and trip the mains supply switch OFF.
Procedure:
1.
Complete a
Visual Inspection
. For details refer to the
First Test
section. If the device passed the
Visual Inspection, continue with the following instructions, if not, refer to the
First Test
section.
