Once polyphase power is available, it may be converted to any desired number of phases with a suitable arrangement of transformers. Thus, the need for more than three phases is unusual, but higher phase numbers than three have been used. Between 1992 and 1995, New York State Electric & Gas operated a 1.5 mile converted from a double-circuit 3-phase 115KV transmission line to a 93KV 6-phase transmission line. The primar… WebFeb 1, 2024 · The maximum detectable velocity of high-frame-rate color flow Doppler ultrasound is limited by the imaging frame rate when using coherent compounding techniques.
