The transformer is used to convert the incoming voltage at the location to the correct voltage (for the submersible motor in case of ESP). Transformer selection is based on mainly 4 parameters:
- Power rating in KVA (Kilo Volt Amperes),
- Primary voltage,
- Secondary voltage,
- Tap arrangement.
Power rating in KVA for three phase transformer:
The calculation of power rating in KVA for a Three Phase Transformer is based on Winding Voltage and Amperage information. The simple formula to calculate the rating of three phase transformers is:
KVA = (√3. V x I) /1000
Refer to the post titled “How to Calculate the Required KVA Rating for three Phase Transformers? ” for more details.
