equal to 100% of rated power and that the reactive power is equal to 0% of
rated power.
3.
Change the angle between the injected current and voltage to
Angle1
+ 90°.
Check that the monitored active power is equal to 0% of rated power and that
the reactive power is equal to 100% of rated power.
4.
Change the angle between the injected current and voltage back to
Angle1
value. Increase the current slowly from 0 until the START1 signal, start of
stage 1, is activated. Check the injected power and compare it to the set value
Power1
, power setting for stage 1 in % of
Sbase
.
5.
Increase the current to 100% of
IBase
and switch the current off.
6.
Switch the current on and measure the time for activation of TRIP1, trip of
stage 1.
7.
If a second stage is used, repeat steps
for the second stage.
6.3.12.2
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/Current/GOPPDOP(32,P>)/X:GOPPDOP
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.

Testing voltage protection functions
6.4.1
Two step undervoltage protection UV2PTUV
Prepare the IED for verification of settings as outlined in
Values of the logical signals for UV2PTUV are available on the local HMI under
Main menu/Tests/Function status/Voltage/UV2PTUV(27,2U<)/1:UV2PTUV
.
The Signal Monitoring in PCM600 shows the same signals that are available on the
local HMI.
6.4.1.1
Verifying the setting
Verification of START value and time delay to operate for Step1
1.
Check that the IED settings are appropriate, especially the START value, the
definite time delay and the
1 out of 3
operation mode.
2.
Supply the IED with three-phase voltages at their rated values.
3.
Slowly decrease the voltage in one of the phases, until the START signal
appears.
4.
Note the operate value and compare it with the set value.
5.
Increase the measured voltage to rated load conditions.
