When a long-time client approached FCX about needing a frequency converter of this size, FCX Systems had all hands-on deck. The 3MVA was the largest, single frequency converter every built by FCX.
“The equipment is a solid state frequency converter, it’ll take the incoming utility power of 60 hertz and convert it to a 50 hertz output power. Rating is 3 MVA, brings in four 80 volt, 60 hertz power and outputs a 400 volt, 50 hertz power–largest we’ve ever built here. The equipment is actually larger than what we have, the power we have available in the building, so we had to rent generators. We have three megawatts worth of generators sitting outside and we also have to connect large rented load banks up to supply the load to the equipment. Once we got everything connected up, then flipped the input power onto the unit and just slowly start turning on different parts of the equipment, making sure everything works to finally get up to the output of the unit. Then you start adding the load and again, little bits at a time, until you get it up to three megawatts.
This is a customer that we’ve had many jobs with over the years and when they needed something of this magnitude, it was obvious that they wanted to come to us to get the job done. The entire company had hands on getting this built and tested, and we’ll eventually get it shipped from sales to engineering, to purchasing, production, testing, shipping, as the biggest thing we’ve ever done. The biggest single frequency converter we’ve ever built. It’s going to take everybody here to get a job like this complete. This was definitely, definitely, an accomplishment for the whole company, so we’re very proud of putting something like this together from West Virginia.”
