Page 14: Sequence Of Operations - V1 Style Switchgear
15kV Class Padmount VisoVac™ Sequence of operations – V1 Style Switchgear V1 style padmount switchgear only comes with vacuum interruption. VFI ways and switch ways can only be opened and closed. Electrical interconnections vary depending on the application. In this position, the vacuum interrupters are CLOSED. This Model 9-V1example assumes all ways are energized and SW-1 is the only source way. -

15kV Class Padmount VisoVac™ Sequence of operations – V3 Style Switchgear Source way operation example V3 style padmount switchgear comes with vacuum interruption, a visible isolation switch and visible grounding position. VFI ways and switch ways can only be opened and closed. Electrical interconnections vary depending on the application. - Page 16 15kV Class Padmount VisoVac™ In this position the vacuum interrupter and the visible isolation rods are OPEN. The grounding position is OPEN and the visible isolation between the internal load bus and the cable is achieved. See Figure 26. WARNING The ground rods will ground the cables connected to the bushings on each associated way .

15kV Class Padmount VisoVac™ Sequence of operations – V3 Style Switchgear Load way operation example The following sequence of operations shows the energized and de-energized state of the gear as each operation is completed. Note the example assumes switchgear is fed from a single source. Source way (SW-1) not shown is CLOSED. All other ways on the gear (VFI-1+) are considered VFI load ways and are shown. - Page 18 15kV Class Padmount VisoVac™ In this position, the load way vacuum interrupters and visible isolation rods are OPEN. The grounding position is OPEN. This example assumes all load ways (VFI-1) are de-energized and there are no load side sources. The source way (SW-1) is closed.
