Transformer Ratio Calculator

Introduction

Calculating transformer ratios is essential in electrical engineering, and a Transformer Ratio Calculator simplifies this process. In this article, we’ll provide a simple yet powerful HTML and JS code for a Transformer Ratio Calculator.

How to Use

To use the Transformer Ratio Calculator, follow these steps:

1. Enter the primary voltage (Vp) in the input field labeled “Primary Voltage.”
2. Input the secondary voltage (Vs) in the corresponding field.
3. Click the “Calculate” button to obtain the transformer ratio.

Formula

The formula for calculating the transformer ratio (TR) is:

TR=Vs​Vp​​

Where:

• $TR$ is the transformer ratio.
• Vp​ is the primary voltage.
• Vs​ is the secondary voltage.

Example

Let’s consider an example:

• Primary Voltage (Vp​): 240V
• Secondary Voltage (Vs​): 120V

Using the formula:

TR=120240​=2

Therefore, the transformer ratio is 2.

FAQs

Q1: Can I use decimal values for voltages?

A1: Yes, the calculator accommodates decimal values for both primary and secondary voltages.

Q2: What if I input non-numeric values?

A2: The calculator will prompt you to enter valid numeric values.

Q3: Can I use this calculator for three-phase transformers?

A3: No, this calculator is designed for single-phase transformers only.

Conclusion

The Transformer Ratio Calculator provides a quick and accurate way to determine the transformer ratio based on the input voltages. Whether you’re a student or a professional in the field of electrical engineering, this tool can save time and ensure precise calculations.
