Figure 62. Wiring diagram for Type B VR-32 regulator and CL-7 control with differential potential transformer
Notes:
1. Portions of schematic shown in dotted enclosure is located in
regulator tank.
2. Motor resistor required for QD3 tap-changer only. Connection is
direct for QD5 and QD8 tap-changers.
3. This switch is normally closed for QD3 and normally opened for
QD5 and QD8 tap-changers.
4. The two JBB-G points shown are physically one connection point in
the junction box.
