kVA Tools | About

kVA Tools is a free and ad-free suite of electrical design calculators that started as a Transformer Sizing Calculator I built in Excel. Due to Excel's limitations with increasing complexity, I moved it to a more versatile webpage. The suite now includes:

• Arc Flash Calculator
• Battery Sizing Calculator – IEEE 485
• Battery Sizing Calculator – IEEE 1013
• Cable Sizing Calculator – IEC
• Cable Sizing Calculator – NEC
• Transformer Load Gauge
• Transformer Sizing Calculator
• Voltage Drop Calculator

You can support this project by either using the calculators providing feedback or by donating. My name is Chris Ren, an Electrical Engineer of over 12 years. Don't hesitate to email me at cren1@protonmail.com or follow kVATools on Twitter @kVATools.
