4.2.2 Test of phase
difference
The phase difference is set at 45° on the MMI, and the test should verify
that operation is achieved when the PhaseDiff (phase difference) is lower
than 45°.
1 Set these MMI settings:
2 Test with PhaseDiff = 0°
Apply voltages U-line (UL1) = 100% U
r
/sqr3 and U-bus (U5) = 100%
U
r
/sqr3, with a phase difference equal to 0° and a frequency differ-
ence that is lower than 50 mHz.
Check that the SYN1-AUTOOK and SYN1-MANOK outputs are
activated.
3 The test can be repeated with other PhaseDiff values to verify that the
function operates for values lower than the set ones. By changing the
phase angle on U1 connected to U-bus, between +/- 45°. You can
check that the two outputs are activated for a PhaseDiff lower than
45°. It should not operate for other values. See Fig. 11.
