Example characteristic
Non-directional ground fault current protection
Procedure
1.
Measure that the operate current is equal to the
INNonDirPU
setting.
The function activates the BFI_3P and STDIRIN output.
2.
Measure the operate time of the timer by injecting a current of 200% of the
operate value.
3.
Compare the result with the expected value.
The expected value depends on whether definite time
tINNonDir
or inverse time
was selected.
4.
Continue to test another function or complete the test by setting the test mode to
Disabled
.
Residual overvoltage release and protection
Procedure
1.
Measure that the operate voltage is equal to the
VN_PU
setting.
The function activates the BFI_3P and STUN signals.
2.
Measure the operate time by injecting a voltage 1.2 timers set
VN_PU
operate value.
3.
Compare the result with the set
tVN
operate value.
