1. What is the Turns Ratio in Transformer Ratio Method?

The turns ratio is a fundamental parameter in transformer design and analysis that represents the ratio of the number of turns in the secondary winding to the number of turns in the primary winding. It determines the voltage transformation ratio between the primary and secondary sides of the transformer.

2. How Does the Calculator Work?

The calculator uses the turns ratio formula:

Where:

• \( \eta \) — Turns Ratio
• \( N_s \) — Secondary Winding Turn Numbers
• \( N_p \) — Primary Winding Turn Numbers

Explanation: The formula calculates the ratio by dividing the number of turns in the secondary winding by the number of turns in the primary winding.

3. Importance of Turns Ratio Calculation

Details: The turns ratio is crucial for determining voltage transformation, current transformation, impedance matching, and overall transformer performance in electrical systems.

4. Using the Calculator

Tips: Enter the number of turns in the secondary winding and primary winding. Both values must be positive integers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What does the turns ratio indicate?
A: The turns ratio indicates how much the transformer will step up or step down the voltage from primary to secondary side.

Q2: How is turns ratio related to voltage ratio?
A: For an ideal transformer, the voltage ratio equals the turns ratio: \( \frac{V_s}{V_p} = \frac{N_s}{N_p} \).

Q3: What is a typical turns ratio range?
A: Turns ratios can vary from less than 1 (step-down transformers) to greater than 1 (step-up transformers), depending on the application.

Q4: How does turns ratio affect current?
A: For an ideal transformer, the current ratio is inversely proportional to the turns ratio: \( \frac{I_s}{I_p} = \frac{N_p}{N_s} \).

Q5: Can turns ratio be less than 1?
A: Yes, a turns ratio less than 1 indicates a step-down transformer where the secondary voltage is lower than the primary voltage.
