Four Fast Transformer Calculations
Distribution transformer calculations spreadsheet provides fast calculations for the following: Determining the MV/LV transformer rating, calculating overcurrent protection device rating on the low voltage side of the transformer, calculating the prospective short circuit current and Calculating natural ventilation openings sizes required for the transformer room.
1. Determining the MV/LV transformer rating
Input parameters:
- Primary rated voltage (kV.)
- Secondary rated voltage (kV.)
- Max. demand load (kW)
- Power factor after correction
- Transformer type
- Permissible loading percentage (%)
- The nearest standard transformer rating (KVA)
2. Calculating overcurrent protection device rating on the low voltage side of the transformer
3. Calculating the prospective short circuit current across the low voltage side of the transformer
4. Calculating natural ventilation openings sizes required for the transformer room.

I desire that you will help me improve based on the how technology has advanced.
it is simply great
EEP is the best way I have to update my knowledge in electrical engineering. This article is a sample of the great value of EEP in the world.
This is so helpful. Thank you for this.
But is would be better if you can define the terms use next time because of beginners. Thank you once again.
it’s very good.
I do recommend fellow technicians to make use of the portal. it has been of great value
How can i down load the templates
