A single-phase transformer has 2000 turns on the primary and 800 turns on the secondary.
Its no-load current is 5A at a power factor of 0.20 lagging.
Assuming the volt drop in the windings is negligible,
Determine the primary current and power factor when the secondary current is 100A at a power factor of 0.85 lagging.
What are eddy currents? State how their effect is decreased in transformers. (b) Verify the ef?ciency of a 15 kVA transformer for the following conditions: (i) full load, un
