1. What is a Transformer Calculator?

The Transformer Calculator helps determine unknown values in transformer circuits based on the fundamental transformer equation that relates voltages, currents, and turns ratios between primary, secondary, and tertiary windings.

2. How Does the Calculator Work?

The calculator uses these fundamental equations:

\[ \frac{V_p}{V_s} = \frac{N_p}{N_s} = \frac{I_s}{I_p} \] \[ \frac{V_p}{V_t} = \frac{N_p}{N_t} = \frac{I_t}{I_p} \]

Where:

\( V_p, V_s, V_t \) — Primary, secondary, and tertiary voltages
\( I_p, I_s, I_t \) — Primary, secondary, and tertiary currents
\( N_p, N_s, N_t \) — Primary, secondary, and tertiary turns

Explanation: The calculator uses these relationships to compute missing values when sufficient known values are provided.

3. Importance of Transformer Calculations

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

4. Using the Calculator

Tips: Enter known values for any combination of voltages, currents, or turns. The calculator will determine the unknown values based on the transformer equations. At least two values must be provided for meaningful calculations.

5. Frequently Asked Questions (FAQ)

Q1: What is a tertiary winding?
A: A tertiary winding is a third winding in addition to the primary and secondary, often used for voltage stabilization, harmonic suppression, or providing an additional voltage level.

Q2: How accurate are these calculations?
A: These are ideal transformer calculations. Real transformers have losses (copper losses, iron losses) that affect actual performance.

Q3: Can I calculate power with this?
A: Power can be derived by multiplying voltage and current (P = VI) for any winding, assuming ideal conditions.

Q4: What about three-phase transformers?
A: This calculator handles single-phase transformer calculations. Three-phase transformers require additional considerations for phase relationships.

Q5: Why are turns ratios important?
A: Turns ratio determines the voltage transformation ratio and affects current inversely. It's fundamental to transformer operation.
