Verifying the signals and settings
GUID-B05EE7E5-2360-4036-991A-00747C47A625 v2
Make sure that the function is connected to SMAI function with U2P signal.
Delta supervision function has 6 different modes of operation. Proceed as follows to test the function
in a particular mode.
1.
Set the following parameters:
•
Operation
= On
•
MeasMode
= Phase-to-ground
•
Umin
= 10% of
UBase
•
DelU>
= 50% of
UBase
•
DelUang>
= 10°
•
DeltaT
= 2
•
tHold
= 100
2.
Set the constant voltage input of UL1 = 63.5V at 0° and UL2 = 63.5V at 180° secondary at
rated frequency.
3.
Based on the mode of operation, carry out the following changes on input condition of Step
to
detect start condition.
Each mode is given for increase and decrease operation. (3-a and 3-b)
Step No.
OpMode
Changes after step 2
Expected output
3-a
Instantaneous 1
cycle or
Instantaneous 2
cycle
Change UL1 to 20V
STL1 , STLOW, START signal should be
TRUE for 100 ms
3-b
Instantaneous 1
cycle or
Instantaneous 2
cycle
Change UL1 back to 63.5V
STL1 , STRISE, START signal should be
TRUE for 100 ms
3-a
RMS or DFT Mag
Change UL1 to 20V
STL1, STLOW, START signal should be
TRUE for 100 ms
3-b
RMS or DFT Mag
Change UL1 back to 63.5V
STL1 , STRISE, START signal should be
TRUE for 100 ms
3-a
DFT Angle (vector
shift)
Change UL1 to 63.5V at
15° without changing
frequency
STL1, START signal will be TRUE for 100
ms.
3-b
DFT Angle (Vector
shift)
Change UL1 to 63.5V at 0°
without changing frequency
STL1, START signal will be TRUE for 100
ms
4.
Repeat Step
with UL2 changes for different mode.
10.8.3.3
Completing the test
GUID-2FE5E5F0-0E6C-499E-93D2-471C183B89BF v2
Continue to test another function or end the test by changing the
TestMode
setting to
Off
. Restore
connections and settings to their original values, if they were changed for testing purposes.
