Selection Examples, PRCD-S Test Sequence (3-phase) –
18 Test Steps
Simulation of Interruption (steps 1 to 10)
Reversed Conductor Simulation (steps 11 to 16)
Simulation of PE to Phase (step 17)
Measurement of Protective Conductor Current with a Current
Clamp Transformer (step 18)
Semi-Automatic Changing of Fault Simulations (Statuses)
As an alternative to manual sta-
tus changing via the parameters
menu for the respective PRCD
selection at the test instrument
(PRCD-S 1~, PRCD-K 1~ or PRCD-
S3~), quick and convenient
switching amongst the fault
simulations is also possible. The
AUTO status parameter has to
be selected to this end. After
responding to the visual inspec-
tion prompt and saving the
results, automatic switching to
the next fault simulation ensues.
Skipping Test Steps
Test steps can be skipped during fault simulation by pressing the
I
N
key at the test instrument or the test plug.
