How many steps do step regulators usually provide?

Step regulators are devices used in power distribution systems to control voltage levels by adjusting the taps on a transformer. The number of steps a step regulator typically provides is significant because it determines the granularity of voltage adjustments that can be made to maintain optimal performance within the electrical network.

In most cases, step regulators are designed to offer a range of 32 steps. This configuration enables precise voltage control and makes it possible to fine-tune the output voltage in smaller increments, allowing for effective management of fluctuations and maintaining system stability. This degree of control is crucial for ensuring that the voltage supplied to consumers remains within safe and efficient operating limits.

The other choices reflect common configurations, but they do not provide the same level of adjustment as 32 steps. Hence, the correct answer reflects the standard design for step regulators, emphasizing their capability for refined voltage control in power distribution systems.
