Protective Elements
Commissioning: Inrush
Dependent on the parameterized inrush-blocking-mode (
»
1-ph Blo or 3-ph
Blo«), the test procedure is different.
For mode
»
1-ph-Blo« the test has to be carried out first for each individual
phase and then for all three phases together.
For mode
»
3-ph-Blo« the test is a three-phase one.
Object to be tested
Test of inrush blocking
.
Necessary means
three-phase current source with adjustable frequency
three-phase current source (for the first harmonic)
Procedure (dependent on the parameterized blocking mode)
Feed the current to the secondary side with nominal frequency.
Feed abruptly current to the secondary side with double nominal frequency. The amplitude must exceed the
preset ratio/threshold
»
IH2/IN«.
Ascertain that the signal »I
NRUSH
A
LARM
« is generated now.
Successful test results
The signal »I
NRUSH
A
LARM
« is generated and the event recorder indicates the blocking of the current protection
stage.
