Transformer Wire Size Calculator









Wire Size (mm²):

 

Introduction

In today’s world of electrical engineering, precise calculations are essential for ensuring the safety and efficiency of electrical systems. Calculating the appropriate wire size for transformers is a crucial step in this process. To simplify this task, you can create an HTML-based Transformer Wire Size Calculator. In this guide, we will walk you through the process of building one from scratch.

How to Use?

To use the Transformer Wire Size Calculator, you need to input the following parameters:

  • Power (kW): Enter the power rating of the transformer in kilowatts (kW).
  • Voltage (V): Specify the voltage in volts (V).
  • Power Factor: Provide the power factor (PF) of the transformer.
  • Efficiency: Input the efficiency (η) of the transformer.

Once you’ve filled in these values, the calculator will determine the required wire size in square millimeters (mm²).

Formula

The formula used to calculate the wire size (WS) is as follows:

WS = √(P / (1.732 * V * PF * η))

Where:

  • WS: Wire Size (mm²)
  • P: Power (kW)
  • V: Voltage (V)
  • PF: Power Factor
  • η: Efficiency

Example

Let’s illustrate how to use the Transformer Wire Size Calculator with an example:

Suppose you have a transformer with the following specifications:

  • Power (kW): 50 kW
  • Voltage (V): 480 V
  • Power Factor: 0.9
  • Efficiency: 0.95

Using the formula, you can calculate the wire size:

WS = √(50 / (1.732 * 480 * 0.9 * 0.95)) ≈ 3.28 mm²

So, for this example, the required wire size is approximately 3.28 mm².
