Figure 4 13: Example of contact voltage measurement results
Displayed results:
Uc
Contact voltage
Rl
Fault loop resistance
Limit
Limit earth fault loop resistance value according to BS 7671.
Notes:
•
Parameters set in this function are also kept for all other RCD functions!
•
The measurement of contact voltage does not normally trip an RCD. However, the trip limit may
be exceeded as a result of leakage currents flowing through the PE protective conductor or a
capacitive connection between the L and PE conductor.
•
RCD trip-lock sub-function (function selected to
LOOP RCD
option) takes longer to complete
but offers much better accuracy of a fault loop resistance result (in comparison with the RL sub-
result in
Contact voltage
function).
