Even if it worked with three-phase sine, three-phase line current would have non-sine aberrance and produce harmonic wave-electricity.

即使在三相正弦激励的作用下，三相线电流也将发生非正弦畸变，产生谐波电流。

For electricity you need at least 1, 300 amps over a 240-volt, three-phase line.

FORBES: Money on Tap

Mr. WHITAKER: You could do a query to identify all parcels with a particular zoning designation within so many feet of three-phase electrical power and so many feet of a water line, and the three properties left to put your business or your school would light up.
