The Micro Transformer is a miniaturized measurement device based on the principle of electromagnetic induction. Its core consists of nanocrystalline/ultra-microcrystalline magnetic cores and high-precision windings. When a current-carrying conductor passes through the magnetic core, the magnetic flux generated by the alternating current induces a precisely scaled-down current signal in the secondary winding. Through unique structural design, it achieves picosecond-level response speed for accurate signal transmission.
