Sweep Frequency Response Analyzer Sfra Analysis SFRA Test on Transformer
Power Transformer Winding Deformation Test Machine Sfra Test Kit
Introduction
Sweep Frequency response analysis, or SFRA, is a powerful tool to ensure the integrity of a power transformer. It is typically used to detect if the core and winding assembly has electrically or geometrically changed due to a short-circuit fault or a relocation. Furthermore it is used for routine diagnostic measurement, and for further diagnosis, if routine testing or monitoring identify irregularities.
A frequency response analyzer generates a signal with a certain frequency and a certain amplitude. The response of the electrochemical system to this signal is also a periodic signal. The frequency response analyzer measures both amplitudes and the phase shift (the time difference between the transmitted and received signal.
In electrochemical research, a frequency response analyzer is used to measure the electric current response as reaction to an applied potential wave. The magnitude allows calculating the impedance. You can do this for example with our GDRZ-902 potentiostat/galvanostat that has EIS capabilities.
Advantages of a Frequency Response Analyzer
A major advantage is the predictive value of tests that are made using a frequency response analyzer. A SFRA test (i.e. a frequency scan) does not take much time at all, while testing for corrosive properties by salt spray tests takes a very long time.
