The Current circuit supervision function CCSRDIF (87) is conveniently tested with the
same three-phase test set as used when testing the measuring functions in the IED.
The condition for this procedure is that the setting of
IMinOp
is lower than the setting
of
Pickup_Block
.
6.7.1.1
Verifying the settings
1.
Check the input circuits and the operate value of the
IMinOp
current level
detector by injecting current, one phase at a time.
2.
Check the phase current blocking function for all three phases by injecting
current, one phase at a time. The output signals shall reset with a delay of 1
second when the current exceeds 1.5 ·
IBase
.
3.
Inject a current 0.1 ·
IBase
to the reference current input IREFSMPL.
4.
Increase slowly the current in one of the phases current input and check that
FAIL output is obtained when the current is about 0.9 ·
IBase
.
6.7.1.2
Completing the test
Continue to test another function or end the testing by setting the parameter
TestMode
to
Disabled
under
Main menu/Tests/IED test mode/1:TESTMODE
. If another
function is tested, then set the parameter
Blocked
to
No
under
Main menu/Tests/
Function test modes/Secondary system supervision/CCSRDIF(87,INd)/
X:CCSRDIF
for the function, or for each individual function in a chain, to be tested
next. Remember to set the parameter
Blocked
to
Yes
, for each individual function that
has been tested.
6.7.2
Fuse failure supervision SDDRFUF
Prepare the IED for verification of settings as outlined in
.
Values of the logical signals for SDDRFUF are available on the local HMI under
Main
menu/Tests/Function status/Secondary system supervision/SDDRFUF/
1:SDDRFUF
. The Signal Monitoring in PCM600 shows the same signals that are
available on the local HMI.
The verification is divided in two main parts. The first part is common to all fuse
failure supervision options, and checks that binary inputs and outputs operate as
expected according to actual configuration. In the second part the relevant set operate
values are measured.
