Reduce time and effort assessing your transformer’s condition by using Sweep Frequency Response Analysis. This test method reduces the need for detanking your transformers during diagnostics, and can detect faults in core and windings conveniently.
The Doble M5400 Sweep Frequency Response Analyzer features high accuracy, bandwidth, resolution, sensitivity and dynamic range, allowing you to conduct transformer troubleshooting and maintenance checks quickly and accurately.
Features and Benefits of the Doble M5400
• Wide frequency range. Provides frequency-response measurement from 10 Hz to 25 MHz; the default range (20 Hz to 2 MHz) covers the most important diagnostic areas: core and magnetic properties; winding movement and deformation; and interconnections (leads and tap changers).
• High resolution. Measures frequency response at logarithmically spaced intervals of 1.2% with a constant excitation level and can auto-scale each measurement, providing an overall dynamic range of 80 dB with ±1 dB accuracy, for the highest combination of dynamic range and accuracy.
• Repeatable tests. Frequency response measurements are highly repeatable; even subtle changes can be used for diagnosis.
• Rugged and portable. Rugged construction provides the accuracy of a laboratory instrument with the ability to withstand harsh field conditions and robust test leads to handle the rigors of site testing.
