Single phase device voltage on the secondary side is still 230V, just 230V single phase (phase to phase, not phase to neutral) Sorry, I should have made that clear to start with.
Is not a valid assumption that a 75kVA 3 Phase transformer is really just three 25kVA single phase transformers connected together? I know, for example, that my utility company will set three 50kVA single phase transformers (cans) on a pole to deliver 150kVA of power to me.
In the case of a...
It sounds like you have two scenarios; 1) A Fault Condtiton and 2) Maintenance.
The Fault Condition requires a coordination study to see under which conditions and in what order your breakers will trip. A coordination study is easier if you have software tools such as EasyPower or ETAP...
This is a question that has sparked some debate around here so any input will appreciated. How does one go about calculating how much single phase current is available from a three phase transformer? For example, if I have a 75kVA 230V 3 Phase transformer, what is the maximum single phase load...
