Calculating PSCC?

08/05/2008 8:44 AM

Anyone,

All that responded to my previous query on Isolation Tranformer Earthing I wish to say Thank you too.

My follow on query is how to calculate the PSCC for a three phase system at 400V with a resistance of 0.93 Ohms. The secondary side is earth free thus my earlier question on creating a earth farm?

Thank you in advance for all responses.

Kind Regards

Nadeem

Please be more specific Do you mean fault current calculations,and what do you mean by resistance of 0.93 ohms ,we normally have transformer impedence.

How is the mode of connection Delta/star,etc.?
