• The measurement is stopped if a contact voltage is present on the metal part of the
test object. The warning can be seen on picture on right side.
• If contact voltage is not present (below limit), RPE measurement is started.
Polarity reversal is automatically applied, and the highest measured value (of both
measurements) will be taken as final value.
• Next test, after successful R
PE
test, is about protective conductor current I
LEAK
– it
is performed as a continuous measurement (30 sec, max.). By pressing the button
(7), measurement can be stopped anytime.
• If measured value is lower than the limit, beside the “I
LEAK
” symbol will be displayed
a tick symbol.
•
“PASS” will be shown on the display if whole test is successfully finished.
• If the button (7) is pressed without connecting the If 16 A CEE adapter is not
connected to the GT-6000 v2, and button (7) is pressed, the following warning is
displayed is warning which can be seen on picture on the right side.
DUT must be placed on insulated surface. If that is not the case, possible leakage currents to earth will
disrupt the measurement and accuracy.
f) Testing of RCDs
30 mA residual current circuit breakers RCCBs/RCDs
• The GT-6000 v2 supports tripping time measurement of permanently installed RCCBs/RCDs and portable RCCBs/
PRCDs with a rated residual current of 30 mA. The tripping time is measured with 2 different current settings in the
automatic test sequence: the single rated fault current (initial polarity 0°/180°) and the five-fold rated fault current
(initial polarity 0°/180°).
• Maximum contact voltage is always compared with limit value of 50 ; If value of Contact voltage is above limit,
displayed is the symbol “UB > 50 V” and the test will be stopped.
On next should be put attention:
- Possible leakage currents (after RCCB/RCD)
- Presence of the other earthing equipment
- Some devices (placed after RCCB/RCD) can cause a longer tripping time, e.g., rotating machines,
capacitors etc.
