Transformer Primary And Secondary Current Calculator . V s = secondary coil voltage. I p r i m a r y = p k v a 3 v p r i m a r y. Current Transformer Basics Understanding Ratio, Polarity, and Class from testguy.net Secondary current = 139.1 amperes. Current on the secondary (side 415 v) side will be calculated as follow: Transformer secondary winding ns = 1500.

Transformer Fault Current Calculation . Renewable energy, der, and smart grid. X/r ratio at the utility transformer. Transformer Available Fault Current from www.invbat.com By steven mcfadyen on july 1st, 2012. We get maximum value because the source and any other impedances are ignored or considered. Use a clamp on ammeter to measure the primary current if the load is connected to the secondary is known & the secondary voltage is known or can be measured & the prim to sec ratio of transformer is known.
