The waveform of 230 V and 50 Hz compared with 120 V and 60 Hz. The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the nominal frequency of the oscillations of alternating current (AC) in a wide area synchronous grid transmitted from a power station to the end-user.
NEMA 5-15P 110 V 190 V 60 Hz Uruguay: C, F, I, L 230 V 380 V 50 Hz Type I was the main standard until the 1990s, and still appears in old installations. Uzbekistan: C, E, F 220 V 380 V 50 Hz Vanuatu: C, G, I AS/NZS 3112 230 V 400 V 50 Hz Venezuela: A, B 120 V 208 V 240 V 115/220 V 220/440 V 230/460 V [73] 60 Hz Vietnam
Mains hum, electric hum, cycle hum, or power line hum is a sound associated with alternating current which is twice the frequency of the mains electricity.The fundamental frequency of this sound is usually double that of fundamental 50/60 Hz, i.e., 100/120 Hz, depending on the local power-line frequency.
Some lines in the United States have been electrified at 12.5 kV 60 Hz or converted from 11 kV 25 Hz to 12.5 kV 60 Hz. Use of 60 Hz allows direct supply from the 60 Hz utility grid yet does not require the larger wire clearance for 25 kV 60 Hz or require dual-voltage capability for trains also operating on 11 kV 25 Hz lines.
A few projects are underway to increase the electricity transfer between the 50 Hz (eastern Japan) and 60 Hz networks (western Japan) which will improve power reliability in Japan. [11] In April 2019, Hitachi ABB HVDC Technologies secured an HVDC order for the Higashi Shimizu project to increase the interconnection capacity between the 60Hz ...
