Reactive Energy Converter

What is Reactive Energy?

Reactive Energy is the portion of electricity that does not perform real work but is required to maintain electric and magnetic fields in AC circuits.

It is measured in Volt-Ampere Reactive Hours (VARh).

 

Why Use a Reactive Energy Converter?

• Quickly convert between VARh, kVARh, MVARh, and GVARh.
• Essential for power engineers, electricians, and students.
• Useful in power quality monitoring and billing systems.

 

 Common Use Cases

• Power utilities – Monitoring reactive energy consumption.
• Industries – Calculating penalties for poor power factor.
• Engineers & students – Electrical design and load studies.

 

 How to Use the Reactive Energy Converter

1. Enter the reactive energy value.

2. Select the input unit (VARh, kVARh, MVARh, etc.).

3. Instantly get the conversion in all supported units.

 

 Supported Units

• Volt-Ampere Reactive Hour (VARh) – Base unit.
• Kilovolt-Ampere Reactive Hour (kVARh) = 1,000 VARh
• Megavolt-Ampere Reactive Hour (MVARh) = 1,000,000 VARh
• Gigavolt-Ampere Reactive Hour (GVARh) = 1,000,000,000 VARh

 

Example Conversions

• 1 kVARh = 1,000 VARh
• 1 MVARh = 1,000 kVARh
• 1 GVARh = 1,000 MVARh
• 500,000 VARh = 0.5 MVARh

 

Who Uses This Tool?

• Electrical Engineers – Power factor and reactive energy compensation.
• Utilities & Industries – Monitoring and billing reactive energy.
• Students & Researchers – Learning about AC circuits and energy flow.

 

 FAQs

1. What is the unit of reactive energy?

Reactive energy is measured in Volt-Ampere Reactive Hours (VARh).

2. What’s the difference between active and reactive energy?

Active Energy (kWh): Does useful work (lighting, heating, motors).

Reactive Energy (kVARh): Supports magnetic & electric fields, but doesn’t perform work.

3. Why do utilities charge for reactive energy?

Because excessive reactive energy lowers efficiency and increases grid losses.

4. How do you calculate reactive energy?

Reactive Energy = Voltage × Current × sin(ϕ) × Time

5. Is this converter free?

Yes – 100% free and online.
