What is battery discharge tester ?

A battery converts chemical energy into electrical energy by creating a potential difference between two electrodes (anode and cathode) through a chemical reaction.

When a battery is discharged, electrons flow from the anode to the cathode while ions in the electrolyte move to maintain charge balance; when it is charged, the process is reversed.

What is  SFRA test?

Sweep Frequency Response Analysis (SFRA) test is an important measurement method used to assess the mechanical and electrical integrity of power transformers. It tests the mechanical integrity of transformer cores, windings, and press frames by measuring the voltage transfer function over a wide frequency range. Each electrical network has a unique frequency response called a frequency response fingerprint.
