Test Sequences for Documenting Fault Simulations at type S and K PRCDs
with the Optional PROFITEST PRCD Adapter
• There are three preset test sequences:
– PRCD-S (single-phase)
– PRCD-K (single-phase)
– PRCD-S (3-phase)
• The test instrument runs through all test steps
semi-automatically:
Single-phase PRCDs: PRCD-S: 11 test steps
PRCD-K: 4 test steps
3-phase PRCDs: PRCD-S: 18 test steps
• Each test step is evaluated and assessed by the user
(go/no-go) for later documentation.
• Measurement of the PRCD’s protective conductor resistance
using the test instrument’s R
LO
function
• Measurement of the PRCD’s insulation resistance using the
test instrument’s R
ISO
function
• Tripping test with nominal residual current using the test
instrument’s I
F
function
• Measurement of time to trip using the test instrument’s I
N
function
• Varistor test for PRCD-K:
measurement via ISO ramp
Further information is available in the data sheet for the PROFITEST
PRCD.
