1. What is the Transformer Equation?

The transformer equation describes the relationship between primary and secondary voltages based on the turns ratio of the transformer. It is fundamental to understanding how transformers work in electrical systems.

2. How Does the Calculator Work?

The calculator uses the transformer equation:

Where:

• \( Primary \) — Primary voltage (V)
• \( Turns\ Secondary \) — Number of turns in secondary coil
• \( Turns\ Primary \) — Number of turns in primary coil

Explanation: The equation shows that the voltage ratio between primary and secondary coils is equal to the turns ratio of the transformer.

3. Importance of Transformer Calculation

Details: Accurate transformer calculations are essential for designing electrical systems, selecting appropriate transformers, and ensuring proper voltage transformation in power distribution networks.

4. Using the Calculator

Tips: Enter primary voltage in volts, number of turns in secondary coil, and number of turns in primary coil. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the ideal transformer assumption?
A: The equation assumes an ideal transformer with no losses, perfect coupling, and equal power on both sides.

Q2: Can this equation be used for step-up and step-down transformers?
A: Yes, the equation works for both step-up (secondary > primary) and step-down (secondary < primary) transformers.

Q3: What are typical turns ratios in power transformers?
A: Turns ratios vary widely depending on application, from small ratios for impedance matching to large ratios for high-voltage transmission.

Q4: How does load affect transformer operation?
A: Under load, real transformers experience voltage drop due to winding resistance and leakage reactance, which the ideal equation doesn't account for.

Q5: What safety precautions should be taken with transformers?
A: Always de-energize before working, use proper insulation, and follow electrical safety protocols when testing or installing transformers.
