Can someone teach me how I can measure the single phase induction motor?
especially the method of measure.

 

make the statement easy,
can someone can teach me how to measure transient current in circuit diagram?

 

Use a storage oscilloscope (digital or analog) and a current transducer. If you make your question more specific, you'll get more specific answers. For example, give an idea of the magnitude of the current and the frequencies/times that are important to you.

 

May I know what is the different between storage oscilloscope and oscilloscope?
