3.3.13 Synchronizing/Reclosing or Synchrocheck Relay
FIGURE 3.19 SYNCHRONIZING RELAY TEST
3.3.13.1 PHASE ANGLE LIMIT TEST.
1.
Make the test connections, as shown above. Ensure the system is selected for Vector mode as indicated
on the F4 line of the Control Module display. If it isn’t, enter the following key sequence: MENU |
Settings | Fault Type | Vector, followed by MENU again to exit the menu.
2.
Enable the AC outputs by pressing ENABLE, and press PREFAULT to activate the outputs. If
necessary, adjust the A and B voltage output levels by selecting them with F1 or F2 respectively, plus
the MODIFY knob or keypad.
3.
Set the phase angle of voltage B to match the phase angle of voltage
Α
(i.e. 0.0
°).
Press F2 on the
voltage module twice so that the flashing cursor appears beneath the
°
symbol on the B voltage line of
the display, and enter the voltage channel A phase reading (i.e. 0.0
°)
via the MODIFY keypad. This
should cause the relay to pick up.
4.
To determine the phase angle limit window, increase and decrease the B voltage phase angle via the
MODIFY knob until the relay drops out.
3.3.13.2 VOLTAGE LIMIT TEST.
1.
If you haven’t done so, perform steps 1-3 in section 3.3.13.1 above.
2.
Select the voltage adjust mode for voltage A by pressing F1 until the flashing cursor lies beneath the
‘V’ on the VA voltage line of the display. Determine the voltage limit window by raising and lowering
the voltage with the MODIFY knob until the relay drops out.
