3-Phase, Single-Phase & DC Power Calculator

Apparent Power (VA):

Real Power (W):

Reactive Power (var):

Our Advanced Power Calculator is a handy tool that makes calculating electrical power easy for everyone. Whether you’re an engineer, an electrician, or just someone curious about electricity, this calculator can help you figure out power in different types of systems. It works with 3-phase, single-phase, and DC (direct current) setups, and it lets you choose how you want to input and see the results. Plus, it comes with a chart to make things even clearer!

What is it?

It is a tool that helps you measure electrical power. Power is the amount of energy an electrical system uses or supplies. This calculator can tell you three important things:

Why is this useful? Knowing these values helps people design electrical systems, fix problems, or even save energy. The calculator works for three types of systems:

How to use it

Using the calculator is simple. Here’s how you can do it step by step:

1. Pick Your System

First, choose the type of system you’re working with:

The calculator will adjust based on what you pick.

2. Enter Voltage and Current

Next, you need to tell the calculator two things:

  1. Volts (V): For smaller systems.
  2. Kilovolts (kV): For bigger systems (1 kV = 1,000 V).
  1. Amperes (A): For smaller currents.
  2. Kiloamperes (kA): For larger currents (1 kA = 1,000 A).

3. Add the Power Factor (For AC Systems)

If you’re working with 3-phase or single-phase (both are AC systems), you’ll need to enter a power factor. This is a number between 0 and 1 that shows how well the system uses power. For example:

For DC systems, you don’t need to worry about this—it’s always set to 1.

4. Choose Your Output Units

The calculator lets you decide how you want to see the results. You can pick:

Think of it like choosing between inches or feet to measure something—it depends on how big the thing is!

5. Hit “Calculate”

Once you’ve entered everything, click the “Calculate” button. The calculator will show you:

It also draws a chart that shows these three values as bars, so you can see how they compare.

What Do the Results Mean?

When you get your results, here’s what they tell you:

The chart—called a power triangle—shows these three values side by side. It’s a great way to picture how they fit together, especially if you learn better by seeing things.

A Real-Life Example

Let’s try using the calculator with something familiar: a single-phase microwave oven in your kitchen.

  1. Apparent Power: 1150 VA
  2. Real Power: 1035 W
  3. Reactive Power: About 501 var

What Does This Mean?

The chart will show three bars: one at 1150 (apparent), one at 1035 (real), and one at 501 (reactive). This makes it easy to see how the power splits up.

Why Is This Calculator So Great?

Here’s why the Advanced Power Calculator is worth using:

It’s perfect for both pros who work with electricity every day and beginners who are just starting to learn.
