What is the primary purpose of a distribution transformer?

The primary purpose of a distribution transformer is to step down voltage for distribution from substations to consumers. In a typical power system, electrical energy is generated at high voltage levels to facilitate efficient long-distance transmission. However, this high voltage cannot be used directly by residential and commercial consumers. The distribution transformer reduces the high voltage received from the substation to a lower, safer voltage suitable for everyday use by customers, allowing for efficient power distribution without risking safety or electrical equipment damage.

This stepping down process is essential for providing electricity at usable voltage levels while maintaining supply integrity. Distribution transformers are placed throughout the electrical distribution system to ensure that consumers receive the correct voltage needed for appliances and fixtures in homes and businesses.
