Tuesday, Feb 12, 2013

DNV KEMA Energy & Sustainabilitytoday recommissioned  and welcomed back its 1000MVA short circuit generator G1 toits DNV KEMA Testing Inspections & Certificationfacilities in Chalfont, PA.  The generator is used to perform high power testing on T&D power products for compliance, performance and safety.

The test generator began an extensive overhaul in early 2011 by a repair facility in Virginia operated by Alstom. According to Paul Leufkens, director of DNV KEMA  Testing, Inspections & Certification , the newly refurbished unit is in top condition and ready for operation.  According to Leufkens, ”We look forward to scheduling  clients who waited patiently for the generator to be back in service to perform high power,  internal arc fault tests of 0.5s and longer.  The machine is now in nearly new condition and ready for clients’ tests.”

Leufkens noted that, ”During the overhaul of the short circuit generator, its driving, cooling and control systems were completely renovated and modernized to provide reliable operation of the complete test system: We refurbished the driving motor, rewound DC super-exciter machines, installed a new oil cooling system, replaced the original main breakers with a modern design to completely update the 1000 MVA test line to meet our customer’s demand and proceed with further facility renovation.The test generator’s rotor and stator were completely rebuilt with modern insulation and laminated iron core.”
