EXAMPLE OF VTOP - OUTDOOR INSTALLATION
VTOP - POWER to RECLOSER and RTU:
Advantages:
- Direct power supply from medium voltage lines
- No need for another step down transformer or low
voltage lines
- Recloser operates independently from any other low
voltage lines that might supply power to the other users
- Eliminates possible power losses to reclosers due to
other users faulting low voltage lines
- Easy installation and maintenance free at remote areas
- Power to wireless protocols for controlling sectioning
distribution networks from control centers
- Tested for extreme winter and summer outdoor
conditions.
- Power to any other equipment up to 1000 VA
