Reactive Power Converter

Master Reactive Power Calculations

Reactive power (Q) is the backbone of AC magnetic fields, yet calculating it across different magnitudes can be tedious. Our Reactive Power Converter eliminates manual math errors by standardizing units instantly. Whether you are sizing capacitor banks, analyzing transformer efficiency, or auditing industrial power systems, accurate conversion between Volt-Amperes Reactive (VAR) and kilovars (kVAR) is essential.

Designed for field technicians and electrical engineers, this tool supports small-scale measurements (VAR) up to utility-grade calculations (MVAR). Ensure your power factor correction data is precise and ready for reporting with a single click.

How to Use

1. Input Data: Enter your measured reactive power value into the "From" field.
2. Select Scale: Choose your source unit (e.g., VAR) and target unit (e.g., MVAR) from the dropdown menus.
3. Calculate: Click "Convert Power" to see the precise equivalent immediately.
4. Copy: Use the "Copy Result" button to save the figure for your engineering logs.

Frequently Asked Questions

What is the purpose of reactive power?

Reactive power generates the magnetic fields required by inductive loads like motors and transformers. Without it, these devices cannot maintain magnetic flux or perform work.

How do you control reactive power?

Engineers use capacitor banks, synchronous condensers, or static VAR compensators (SVCs). These devices inject or absorb reactive power to stabilize voltage levels and improve the power factor.

Can an inverter generate reactive power?

Yes. Smart inverters, particularly in solar PV systems, can synthesize reactive power to support grid voltage stability and assist with ancillary grid services.

What happens if reactive power is high?

Excessive reactive power lowers the system's power factor. This forces conductors to carry more current for the same actual work, causing overheating, voltage drops, and utility penalties.

What are the disadvantages of reactive power?

It occupies grid capacity without doing useful work, increases transmission losses (I²R), requires larger equipment sizing, and often incurs financial surcharges from utility providers.
