Mr. Ricky CasipeWith regards of our test instrument the’re all in Good condition. I'll purchase some instrument sooner. Thank you very much -
Ms. Remy GalaponFrom year 2020 to 2023, we purchased more than 30 equipment from Delta Technology, they are all work well and the service from Delta Technology is also good. -
Mr. MilanThe VLF-80 Tester is perfect and thank you.

Product Description
Sfra 10Hz to 10MHz Sweep Frequency Response Analysis Equipment
Introduction:
- Normally, the structure and reference of transformer is fixed after being made, therefore, the frequency response of each winding will be almost the same. However, under some special conditions, such as cut off between circles or phases during test, cut off or winding moved during running, winding moved in transportation, these conditions may change the structure of transformer , then the frequency response may be changed, we could detect the deformation according to the frequency response curve.
- Our company has designed the SFRA 10MHz Response Analysis Equipment base on the idea and the advanced technique. It could draw the frequency response curve accurately. Then we compare the curves horizontally or vertically to detect the deformation of the transformer.
- SFRA 10MHz Response Analysis Equipment is a powerful and sensitive method to evaluate the core, winding and clamping structures of power transformers, by measuring their electrical transfer functions over a wide frequency range.
