USA, West Virginia: Utility company Potomac Edison has completed equipment upgrades at a substation in Jefferson County, West Virginia, to enhance service reliability and help meet high winter demand for electricity for about 2,200 customers in the Ranson and Charles Town areas.
The centrepiece of the $1 million project was replacing one of the substation's two distribution transformers with a larger unit, which increased the system's capacity without having to expand the substation's footprint or build new power lines, according to the press release.
The substation upgrade also included replacing existing fuses with a new circuit breaker to safeguard the new transformer when irregularities are detected on the electric system.
Substation construction crews used a heavy-duty crane to remove the old transformer through a temporary opening in the substation fence to avoid nearby power lines. After weeks of preparation work, the new transformer was placed into place on its pad.
