Which of the following types of transformers is used in distributing electricity to consumers?

To determine which type of transformer is used in distributing electricity to consumers, we need to consider the options available. The different types of transformers commonly used in power distribution include:

1. Distribution Transformers: These transformers are specifically designed for distributing electricity to consumers. They are typically used in substations to step down the voltage from the transmission level (typically 69 kV or higher) to a lower voltage suitable for distribution (typically 12 kV or lower). Distribution transformers are commonly found on utility poles or in pad-mounted enclosures.

2. Power Transformers: While power transformers are primarily used in transmission systems to step up or step down voltage levels for long-distance power transmission, they can also be used in distribution systems depending on the specific requirements. However, they are less commonly used in distribution compared to distribution transformers.

3. Auto Transformers: Auto transformers are another type of transformer that can be used in power distribution. They have a single winding with multiple taps, allowing for voltage adjustment. Auto transformers are often used in situations where a small voltage adjustment is required, such as in industrial or commercial settings.

Based on the options provided, the most suitable type of transformer used in distributing electricity to consumers is likely the distribution transformer. However, it's important to note that the specific type of transformer used can vary depending on the voltage levels, load requirements, and other factors specific to the distribution system.
