The Doble M5500 Sweep Frequency Response Analyzer investigates the mechanical integrity of transformers, reactors and other equipment with windings. It uses incredibly fast sweep speeds, typically between 15 and 30 seconds, and expanded dynamic range to measure the frequency response of transformers. Fast sweep speeds reduce the time required to conduct SFRA testing, particularly for transformers with complex test plans. Combine the M5500 with Doble's powerful SFRA Software v6 to conduct testing and analysis of results.

Add the lightweight and portable M5500 to your diagnostic toolkit to:

• Pinpoint problems such as core movement, winding deformation and displacement, faulty core grounds, partial winding collapse, hoop buckling, broken or loose clamping structures, shorted turns and open windings.
• Test transformers in the factory as part of your regular maintenance program and after system faults.
• Assess transformer deterioration to determine if it is fit for service after a fault or to identify damage sustained during transit.
