Research on the Transformer Phase Testing Methods
Using the general digital phase transformer is unable to measure the minimum phase of the mutual inductor. This paper introduced the basic principles of using an oscilloscope to measure the minimum phase of the mutual inductor. It gives a measurement method and the steps. It has certain significance to small precision measurement phase transformer.
