What is Understanding Dual Ratio Transformers about?
Dual ratio transformers can be connected to two different voltage sources, such as 33kV and 22kV, with the primary winding designed for both voltage levels through series or parallel configurations to maintain ampere-turn and volts-per-turn balances, while the secondary voltage remains the same; tap changer step sizes will differ between the voltage connections but voltage change per tap remains uniform, and no-load losses are identical but load losses may vary depending on the connected voltage level.
