Transformer Secondary Current Calculator

Single Phase Transformer

1. Select "Single Phase" configuration
2. Enter the transformer KVA rating
3. Input the secondary voltage (line-to-neutral)
4. Click "Calculate" to get secondary current
5. Review the step-by-step calculation

Example: 10 KVA, 240V single phase transformer

Three Phase Transformer

1. Select "Three Phase" configuration
2. Enter the transformer KVA rating
3. Input the secondary voltage (line-to-line)
4. Click "Calculate" to get secondary current
5. Review the detailed calculation steps

Example: 100 KVA, 480V three phase transformer

Important Notes

• KVA rating is the transformer's apparent power capacity
• For single phase: use line-to-neutral voltage
• For three phase: use line-to-line voltage
• Results show full load secondary current
• Consider safety factors for practical applications
