Description

The Project Northeast BioFuels required a number of 13.2kV substations with solidly grounded neutrals and high resistance to work in conjunction with a switchboard style distribution. Motor control and sequencing functionality were key as the control and storage of a substance like ethanol must be handled with careful precision. Our Solution By employing our oil-filled MiniSub design the ethanol plant was able to streamline distribution thanks to the SF6 switch included in the nine MiniSubs strategically located on the grounds.

The Project The work involved the replacement of an existing, outdated substation within a restricted space, without disrupting the existing services. There were two main incoming lines, for normal and alternate feeders, that required secondary distribution panels and metering panels at 416/240V and 208/120V. Our Solution A loop style MiniSub was employed alongwith a separate radial SF6 switch to provide the two service feeders that were key interlocked as per the Utility's operating practices.
