Synchronous Machines. Generally, larger machines have the higher efficiencies because some losses do not increase with machine size. For example, many generators in the 5 MW class and above have efficiencies greater than 97%. But 3% of 5 MW is still 150 kW – and for large units. e.g. 600 MW, 3% of 600 MW is 18 MW!
