1. What is Transformer Ratio?

The transformer ratio is the ratio of the number of turns in the primary winding to the number of turns in the secondary winding. It determines the voltage transformation between the primary and secondary sides of a transformer.

2. How Does the Calculator Work?

The calculator uses the transformer ratio formula:

\[ Ratio = \frac{Primary\ Turns}{Secondary\ Turns} \]

Where:

Explanation: The ratio determines how much the voltage is stepped up or down between the primary and secondary windings.

3. Importance of Transformer Ratio

Details: The transformer ratio is crucial for designing electrical systems, determining voltage levels, ensuring proper impedance matching, and calculating current transformation in power distribution networks.

4. Using the Calculator

Tips: Enter the number of turns in both primary and secondary windings. Values must be positive integers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What does a ratio greater than 1 indicate?
A: A ratio greater than 1 indicates a step-down transformer where the secondary voltage is lower than the primary voltage.

Q2: What does a ratio less than 1 indicate?
A: A ratio less than 1 indicates a step-up transformer where the secondary voltage is higher than the primary voltage.

Q3: How does the ratio affect current?
A: The current transformation is inversely proportional to the voltage transformation, following the conservation of energy principle.

Q4: Can the ratio be exactly 1?
A: Yes, a ratio of 1:1 indicates an isolation transformer where primary and secondary voltages are equal but the windings are electrically isolated.

Q5: What factors affect transformer ratio accuracy?
A: Manufacturing tolerances, core saturation, load conditions, and temperature can affect the actual transformation ratio in practical applications.
