Phase angle check:
•
Set
Va and Vs1 to any value between the SY1OV and SY1UV settings keeping Va in-phase
with Vs1. Then the SYN1 element operates.
•
Shift the angle of Vs1 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 Vs1, and repeat the above.
Synchronism check element SYN2
•
Apply a single-phase rated voltage to terminal 17 and 18 as shown with broken lines in Figure
6.5.1.7 and set the scheme switch [3PH-VT] to "Line". The test can be performed taking the
same step as testing SYN1.
