What is the primary voltage of distribution transformers?

The primary voltage of distribution transformers is commonly around 4.8kV. This level is widely used in distribution systems as it balances efficiency and safety for the delivery of electricity, ensuring effective voltage transformation and minimizing losses during distribution.

Distribution transformers typically take a higher primary voltage and step it down to lower voltages suitable for consumer use. The choice of 4.8kV as a standard helps facilitate widespread connectivity and compatibility within electrical distribution networks, making it an integral part of the infrastructure.

While other voltage levels like 2.4kV, 6.9kV, and 34.5kV exist, they are less commonly used as primary voltages in distribution transformers compared to the 4.8kV standard, which ensures broad applicability and efficiency in urban and suburban electrical systems.
