What is the typical voltage range for secondary voltage leaving a transformer?

The typical voltage range for secondary voltage leaving a transformer predominantly falls within the range of 120 to 240 volts. This range is widely used for residential and commercial electrical systems, as it aligns with standard voltage levels for household appliances and lighting in many regions.

Transformers are crucial in stepping down high transmission voltages to levels suitable for end-user applications, and they often provide outputs of 120 volts for common household circuits and 240 volts for higher-demand appliances. This dual-voltage capability is especially relevant in North America, where 120 volts is commonly used for standard outlets and lighting, while 240 volts is typically utilized for large appliances like dryers and ovens.

Understanding this typical voltage range is essential for utility specialists, as it informs them about the standard operation and safe handling of electrical systems in various settings.
