monitored active power is 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

Completing the test
SEMOD175058-66 v4
Continue to test another function or end the test by changing the
TESTMODE
setting to
Off
. Restore
connections and settings to the original values, if changed for testing purposes.

Measuring the operate and time limit of set values
SEMOD175021-7 v6
1.
Check that the input logical signal BLOCK to the BRCPTOC function block is logical zero and
note on the local HMI that the output signal TRIP from the BRCPTOC function block is equal to
the logical 0.
2.
Set the measured current (fault current) in one phase to about 110% of the set operating
current
IP>
.
Observe to not exceed the maximum permitted overloading of the current circuits in the
terminal.
3.
Switch on the fault current and measure the operating time of BRCPTOC.
TRIP is controlled by Gate 13 in the configuration.
Use the TRIP signal from the configured binary output to stop the timer.
4.
Compare the measured time with the set value
tOper
.
5.
Activate the BLOCK binary input.
