Question: Voltage Regulation in Transformers |
|
Answer: Voltage regulation in transformers is the difference between the no-load voltage and the full-load voltage. This is usually expressed in the terms of percentage: for example, with a transformer that delivers 100 volts at no-load and 95 volts at full-load, the regulation would be 5%. Power and lighting transformers generally have regulation from 2% to 4%, depending on the size and the application for which they are used. For special requirements such as instruments or computers, see the paragraph describing Regulating Transformers. |
