A transformer is important equipment in any electrical circuit. Understanding of transformer repair key terms will help you communicate your transformer problems to repair technicians. If you want to complete transformer repairs on your own, you will need to understand technical terms for the different processes and components in the electrical equipment industry.
This guide covers some important terms that you will hear from companies that provide transformer repair services, including transformer rebuilding, transformer rating and transformer field services.
Transformer field servicesWhen you communicate with companies that provide transformer repairs, they will ask whether you need a transformer field service or if you can ship your transformer.
Transformer maintenanceTransformer maintenance will help you avoid emergency transformer repairs. You must be aware of different tasks that help you to maintain your transformers.
Transformer ratingYou can calculate the rating for your transformer by multiplying the load current by the supply voltage. Some reputable manufacturers of transformers provide explanation on the transformer rating and its units.
Magnetic fieldSince a magnetic field is always associated with a transformer, you should understand the relation between the line current and the magnetic field.
National High Magnetic Field Laboratory provides an interactive tutorial that will help you understand the relation between the line current and the magnetic field in different operating conditions.
Liquid-filled transformersA transformer generates heat while it is working. A liquid-filled transformer is a transformer that contains liquid, mostly oil, for dissipating this heat.
To understand the basics of liquid-filled transformers and their repair process, you can read through information on transformer repairs at R.A.Reed Electric Co. (PDF).
Dry-type transformersUnlike liquid-filled transformers, dry-type transformers do not contain any oil or liquid.
Delcor Power Products, a supplier of industrial transformers, provides basic information and instruction manuals for the different types of transformers, including dry-type transformers.
Step-up transformersA step-up transformer increases voltage from primary to secondary coils. Conversely, you can use a step-down transformer to decrease voltage from primary to secondary coils.
All About Circuits, an information resource that provides information on the basics of electrical equipment, provides details of step-up transformers and the difference between a step-up transformer and a step-down transformer.
