What was the core innovation of Nikola Tesla's polyphase alternating current system?
Answer
The use of two or more independent alternating currents that are out of phase with each other.
The polyphase alternating current system developed by Nikola Tesla utilized multiple independent alternating currents shifted in phase relative to one another. This configuration provided significantly improved efficiency for transferring electrical power across vast distances compared to earlier single-phase attempts. This system allowed for a more balanced and effective delivery of energy, forming the technical backbone of modern power grids.
