Description
The Doble M5400 Sweep Frequency Response Analyzer detects hidden transformer faults using sweep frequency response analysis (SFRA), a proven technique for making accurate and repeatable measurements. System faults, short circuits, aging, or even handling during transportation can compromise a transformer’s mechanical structure. Since these problems are difficult to detect, they usually go unnoticed and worsen over time, leading to loss of performance and possibly failure.
Pioneered by Doble, the sweep approach has become the industry standard and is the preferred method for making frequency domain measurements. With M5400’s non-intrusive test technique, you can test your power apparatus any time you suspect a problem. Or just use it as part of your regular maintenance program. Either way, you identify problems before they lead to failure, such as:
– Core movement
– Winding deformation and displacement
– Faulty core grounds
– Partial winding collapse
– Hoop buckling
– Broken or loosened clamping structures
– Shorted turns and open windings
