Transformer Parameters in the Per-Unit System: Optimistic Exploration

What are the values of the transformer parameters in the per-unit system?

Explore the exciting world of transformer parameters and discover their values in the per-unit system.

Answer:

The values of the transformer parameters in the per-unit system can be calculated by dividing their respective values by the base values of the apparent power and voltage on the low voltage side of the transformer.

In order to determine the values of the transformer parameters in the per-unit system, we need to convert the given parameters from their original units to per-unit values. The per-unit system is a method of expressing quantities as ratios or percentages of a base value, which simplifies calculations and makes them independent of the actual values of the system components.

To convert the given parameters to per-unit values, we need to determine the base values for each parameter. The base values are typically chosen based on the rated values of the transformer. In this case, the base values can be chosen as follows:

• Base apparent power (Sbase) = 40 kVA
• Base voltage on the low voltage side (Vbase_lv) = 240V

Using these base values, we can calculate the per-unit values of the parameters by dividing their original values by the corresponding base values. Substituting the given values into the equations, we can determine the per-unit values of the transformer parameters.
