Transformers are stationary electromechanical devices, the operation of which is based on the fact that any alternating electric field creates a magnetic field. This allows two circuits that are electrically isolated from each other to interact. The current in the first circuit creates a magnetic field around it, which, acting on the second circuit and transferring its energy to it, creates a current in it. This article will show you how to test a transformer. Visually Verify Transformer. Often the cause of the failure of the transformer is the overheating of its internal winding. If the transformer housing is swollen or shows burn marks, please do not check it further. Identify the winding of the transformer. It was expected to have easily readable labels. However, it is often helpful to have a circuit diagram containing your transformer to find out how it is related. The circuit diagram can be found on the product documentation or on the manufacturer's website. Which could be ide
