With the expression inducted from equivalent circuit of transformer using coupling coefficient K, measuring terminal voltage, a calculation of coil coefficient with reapect to turn ratio is proposed. By that methcxi of measuring K, compared with values theorically, this paper confirmed its propriety. With that methcxi of measuring coil coefficient K, having several couple of coil set, we have clarified the characteristic of K according to changing coil's position, programming regression of least square methcxi, and then the expression for function of K is formulated.
