Overview

Sweep Frequency Response Analyzer SFRA Tool for Detecting The M5500 Sweep Frequency Response Analyzer (SFRA) is the newest generation of SFRA diagnostic instrument from Doble. With incredibly fast sweep speed and "Hiddenˮ Transformer expanded dynamic range, you can use the Doble M5500 test set to investigate the mechanical integrity of transformers, reactors, and other equipment with windings.

If you can measure the frequency response of a transformer, then you can identify physical movement and other issues with the winding, core, and connections. The M5500 sends an excitation signal into the transformer and measures the returning signals. Comparing this response to baseline readings and test results from similar units allows you to identify deviations and confirm internal mechanical

The M5500 reduces the uncertainty about apparatus condition by providing solid evidence of mechanical integrity or winding movement. Use it to help determine how a transformer is deteriorating, if it can go back into service after a fault, or if it has been damaged during transit. Specify Doble SFRA baseline testing as part of the factory test for your new transformer and call for retest at every major transportation mode change or crane lift. Use it after system faults and during routine testing as part of your.
