Swinburne Hedgehog Transformer, circa 1890
Add to SetSummary
In 1889, Scottish-born James Swinburne designed a transformer with a core of prickly iron wires. Swinburne claimed his open-circuit "hedgehog" transformer was more efficient than closed-circuit transformers for voltage regulation. Scientists and electrical engineers disputed his assertions and found his innovation was less efficient. Swinburne, however, remained a well-respected member of the engineering field.
