A tool for detecting “hidden” transformer faults

The M5300 detects mechanical failure or movement of windings due to short circuits, mechanical stresses or transportation. Use it to ensure transformer performance, reduce maintenance cost, and increase the service life of transformers.

A major advance in transformer condition analysis.

The M5300 uses Sweep Frequency Response Analysis, a proven technique for making accurate and repeatable measurements. Pioneered by Doble the sweep approach has become the industry standard and is the preferred method for making frequency domain measurements. Here’s how SFRA works: The M5300 sends an excitation signal into the transformer and measures the returning signals across a broad frequency range. By comparing this response to baseline and other results (such as from similar units), you can identify deviations and confirm internal mechanical problems.

DIAGNOSE problems early. PREVENT expensive equipment breakdowns. Take CONTROL.

Why wait for problems to develop? With the M5300’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
