the value at which the element operates. Check that the measured value is within
±
5% of the
setting.
Synchronism check element SYN1
•
Press 4 (= Logic circuit) on the "Test" screen to display the "Logic circuit" screen.
•
Enter a signal number for the TermA line to be observed at monitoring jack A and press the
ENTER key.
•
Apply a three-phase rated voltage and a single-phase rated voltage as shown in Figure
6.5.1.8.
Voltage check:
•
Set the three-phase voltage to any value over the SY1OV setting. (The default setting of
SY1OV is 51V.)
Whilst keeping Vr in-phase with Va, lower the single-phase voltage Vr from the rated value.
Measure the voltage at which the element operates. Check that the measured voltage is within
±
5% of the SY1UV setting.
•
Further lower Vr and measure the voltage at which the element resets. Check that the
measured voltage is within
±
5% of the SY1OV setting.
Phase angle check:
•
Set
Va and Vr to any value between the SY1OV and SY1UV settings keeping Va in-phase
with Vr. Then the SYN1 element operates.
•
Shift the angle of Vr away from that of Va, and measure the angle at which the element resets.
•
Check that the measured angle is within
±
5° of the SY1
θ
setting. (The default setting of SY1
θ
is 30°.)
•
Change
Va and Vr, and repeat the above.
Synchronism check element SYN2
•
Apply single-phase rated voltage to terminals 17 and 18 as shown with broken lines in Figure
6.5.1.8 and set the scheme switch "3PH-VT" to "Line". The test can be performed taking the
same steps as testing SYN1.
