Power Sales Group unites with AMSC

  Power Sales Group is pleased to announce that we will be representing AMSC (American Superconductor Corp) for our entire service territory.  AMSC, based in Devens, MA, offers products and services geared to today’s changing Utility infrastructure.  With the rise of DG, Solar Sites and Wind Farms, AMSC’s DVAR & SVC systems have a proven track record of success. Furthermore, what separates AMSC from the rest is its tremendous in-house engineering staff.  AMSC engineers work with customers and planning engineers from concept, installation, commissioning and preventative maintenance, to ensure complete satisfaction.   AMSC continues to be the pioneer in Super Conducting Cables and Fault Current Limiters. AMSC’s Superconductor Cable Systems replace commonly utilized materials like aluminum and copper with high temperature superconductor (HTS) wire. HTS wiring can increase power transmission by ten times and preforms remarkably well at low voltages. HTS wiring is capable of transmitting direct and alternating currents, ideal for powering anything from data centers to power networks.

Taking preventative measures as such will greatly improve equipment lifespans and reduce or even eliminate certain maintenance requirements. In conjunction with AMSC, successful organizations like Nexans have developed and demonstrated effective SFCL implementation in areas of Europe and North America.

Preventing Switch Failure

Disconnect switches have the important role of isolating circuits and equipment on any modern power grid.  When a switch is open, operators can easily confirm this; however, it is nearly impossible to visually confirm a perfect closed connection. Improperly seated switches have led to switch burn outs and power outages coupled with high costs for utility companies. The idea of a disconnect switch may seem simple, but from the ground, it’s surprisingly difficult to determine if a switch is properly functioning. The issue is the switch blade must establish a high degree of contact pressure between the switch jaws in order to generate the necessary current. Due to inclement weather, defective equipment or operator error, a switch may remain partially open or un-rotated unbeknownst to technicians, causing burnouts and failures. Southern States has solved this issue with a new switch technology called MACI or Magnetically Actuated Close Indicator which provides unambiguous visual confirmation for disconnect switches. A colorful red indicator provides a ‘closed confirmation’ from 100 ft. away MACI provides an unambiguous, binary indicator, which only shows when blade is fully seated and rotated. MACI has magnetically coupled linkage, which ensures the indicator never interferes with switch operation even in severe weather. Watch the video below to see MACI in action.   Highlights -Visibility up to 100 ft. -Magnetic switch that does not interfere with mechanism -Unambiguous binary signal -Retrofitted to any vertical break or any double end break switch -Rated for 245kV and above / 115kV available 1Q16...
