6.4.2.2
Completing the test
Continue to test another function or end the testing by setting the parameter
TestMode
to
Off
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/Voltage/OV2PTOV(59,2U>)/1:OV2PTOV
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.

Two step residual overvoltage protection ROV2PTOV
Prepare the IED for verification of settings as outlined in
Values of the logical signals for ROV2PTOV are available on the local HMI under
Main menu/Tests/Function status/Voltage/ROV2PTOV(59N,2UN>)/
1:ROV2PTOV
. The Signal Monitoring in PCM600 shows the same signals that
are available on the local HMI.
6.4.3.1
Verifying the settings
1.
Apply the single-phase voltage either to a single phase voltage input or to a
residual voltage input with the start value below the set value
U1>
.
2.
Slowly increase the value until ST1 appears.
3.
Note the operate value and compare it with the set value.
4.
Switch the applied voltage off.
5.
Set and apply about 20% higher voltage than the measured operate value for
one phase.
6.
Measure the time delay for the TR1 signal and compare it with the set value.
7.
