In the context of distribution transformers, a common feature is having two secondary windings, which is essential for providing different voltage levels as needed for various applications. These transformers are typically designed to step down high transmission voltages to lower distribution voltages suitable for residential and commercial use.

Having two secondary windings allows for greater flexibility in distributing electrical power. One winding can output a standard voltage level for general use, while the second can provide a different voltage level that might be required by specific equipment or users. This capability ensures that the distribution system can cater to a variety of loads and requirements effectively.

Options like a single secondary winding, high current capacity, and step-up voltage capability apply to some transformer designs but are not considered common features for distribution transformers specifically, as their primary role is to step down voltage rather than increase it, and they are generally designed around various configurations depending on the specific use case.
