1. What is a 220/110 Transformer?

A 220/110 transformer is an electrical device that converts 220 volts to 110 volts or vice versa. These transformers are commonly used for powering equipment designed for different voltage standards or for voltage step-up/down applications.

2. How Does the Calculator Work?

The calculator determines the current on both primary and secondary sides of the transformer based on its kVA rating and voltage configuration.

For Single Phase: Current (A) = (kVA × 1000) / Voltage

For Three Phase: Current (A) = (kVA × 1000) / (Voltage × √3)

3. Importance of Proper Transformer Sizing

Details: Correct transformer sizing ensures efficient power transfer, prevents overheating, and matches your electrical load requirements.

4. Using the Calculator

Tips: Enter the transformer's kVA rating, select primary and secondary voltages, and specify whether it's single or three phase.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between 220V and 110V?
A: 220V systems deliver power at higher voltage with lower current, while 110V systems use lower voltage with higher current for the same power.

Q2: When would I need a 220 to 110 transformer?
A: When you have 220V power but need to operate 110V equipment, or vice versa.

Q3: How do I choose the right kVA rating?
A: Calculate your total load requirements and add 20-25% safety margin.

Q4: Can I use this transformer for step-up and step-down?
A: Most transformers can work both ways, but check manufacturer specifications.

Q5: What's the advantage of three phase over single phase?
A: Three phase is more efficient for larger loads and provides smoother power delivery.
