Frequency response analyzer - M5000 series
The Doble’s M5000 series uses sweep frequency response analysis to detect mechanical failure or movement of windings from short circuits, mechanical stresses, or transportation. The instruments send an excitation signal into the transformer and measure the returning signals. Comparing this response to baseline and other results (such as from similar units) allows you to identify deviations and confirm internal mechanical problems. Use the M5400 Sweep Frequency Response Analyzer to ensure transformer performance, reduce maintenance cost, and increase service life. In addition, The M5300 and M5400 come with intuitive, Windows-based SFRA software that runs on a user-supplied PC (for the M5400) or on the M5300 itself. The software allows you to compare and analyzer SFRA measurements. It also comes with preconfigured templates as a guide to specifying tests for the field.
