Lansdale Electric, Pennsylvania, USA is setting up upgrades for its outdated equipment in order to expand the power network and make it faster, stronger and more flexible.
“They’re still in good working order; it’s just that when something does go wrong, it’s hard to find parts, we’re down for a longer period of time, so this is really going to help us,” said Electric Superintendent Andy Krauss.
“These are good pieces of equipment, they’re just becoming outdated. We got, at the time, the best equipment that was out there, the most efficient equipment that was out there, it’s just that they’re going on 40 years old now or older,” he said.
The update to the equipment will involve nine medium-size electric transformers, capable of handling either 5 or 7.5 MVA, stationed throughout town.
A $ 492,165 contract has recently been awarded to Central Electric Manufacturing Company to build and install a new higher-capacity transformer in October 2014. The new transformer will replace the current one at the Stony Creek substation and will be built to fit the power lines that run in from overhead.
According to Krauss, power runs into town via lines along the railroad tracks near Cannon Avenue on high-capacity lines at 69 kV and is stepped down to 34 kV via a large transformer at Electric Department main substation and finally to smaller substations such as the one at Stony Creek.
The current 5 MVA transformer has one circuit carrying the 4 kV electric line out of the substation and into the nearby neighborhood. The new 7.5 MVA transformer will have two circuits, one to continue down the tracks and another to run beneath the roads and sidewalks of the Andale houses and out to Hancock Street.
The new transformer will be connected to the borough’s fiber optic network so any faults can be identified remotely from the headquarters.
“That will give us better response times, and we’ll be better prepared with our equipment to come out and fix this stuff,” Krauss stated.
Out of the nine transformers in the borough’s network, two have already been upgraded from 5 to 7.5 MVA and the Stony Creek substation will be the third.
“[The Stone Creek transformer] is one of the oldest ones, and that one’s probably in the worst shape,” commented Krauss.
