What are the common faults of small transformers?
(1) Transformer itself problems such as loose ends, loose blocks, poor welding, poor core insulation, and insufficient short-circuit strength.
What are the basic characteristics of transformers?
1. The primary coil is connected in series in the circuit, and the number of turns is very small. Therefore, the current in the primary coil is completely dependent on the load current of the circuit under test. And has nothing to do with the secondary current;
The difference between isolation transformer and transformer
The isolation transformer is a classification method of the transformer. The isolation transformer also works by electromagnetic induction (ie, Lenz's law). The isolation variation in the flat state is such a thing:
