peer agreement (net): +1
peer agreement (net): +1ligne Explanation: or 'pôle' or 'phase' It's referring to the 3 'legs' or phases in a 3-phase star connection; just as in Europe there is 110 V (or 230 V here) between any one phase and neutral (except in one special wiring configuration!), but you can get 208 V (or 380 V) here if you connect instead betwene two phases, which tedn to be called 'legs', most especially in the USA. -------------------------------------------------- Note added at 1 jour1 minute (2017-08-21 11:21:03 GMT) -------------------------------------------------- I don't think there is any possible confusion with a 'transmission line', since the context here is totally explicit and unambiguous. However, if you have even the slightest qualm, you could safely use 'phase' instead ; though FR does also use 'pôle' (even though we are not talking here about anything like a 'switch pole', for example) — we would NOT use 'pole' here in EN, but it is quite common in FR to refer to the 'pôles' of a 3-phase system. |

phase ou sommet (en cas de system high-leg delta) Explanation: "leg" is commonly used for the 240/208/120 V system, called "High-leg delta". High-leg delta (also known as wild-leg, stinger leg, bastard leg, high-leg, orange-leg, or red-leg delta) is a type of electrical service connection for three-phase electric power installations. It is used when both single and three-phase power is desired to be supplied from a three phase transformer (or transformer bank). The three-phase power is connected in the delta configuration, and the center point of one phase is grounded. : High-leg delta service is supplied in one of two ways. One is by a transformer having four wires coming out of the secondary, the three phases, plus a neutral connected as a center-tap on one of the windings. … The voltages between the three phases are the same in magnitude, however the voltage magnitudes between a particular phase and the neutral vary. The phase-to-neutral voltage of two of the phases will be half of the phase-to-phase voltage. The remaining phase-to-neutral voltage will be √3/2 the phase-to-phase voltage. So if A-B, B-C and C-A are all 240 volts, then A-N and C-N will both be 120 volts, but B-N will be 208 volts https://en.wikipedia.org/wiki/High-leg_delta High Leg Delta Si du triphasé est nécessaire, on utilise un autre type de transfo d'alimentation. Chaque utilisateur industriel a sa propre cabine de transformation et on utilise un branchement spécial, ici aussi pour permettre le branchements d'appareils 120V et 240V: “high leg delta”. Le neutre, au lieu d'être connecté au centre de l'étoile est connecté entre deux phases via le transfo réducteur de tension. Une des phases a donc une tension plus élevée par rapport au neutre (high leg). Le neutre est ici aussi mis à la masse dans la cabine de transformation. : Le triphasé "high leg delta" n'est d'application qu'à partir du dernier transfo (celui qui produit la tension pour les utilisateurs). C'est la mise au neutre spéciale qui fait d'un triphasé normal un triphasé high leg delta http://server.idemdito.org/electro/elec/usa.htm 240 V, 480 V, 600 V, 240/120 V High-Leg Delta / extremo alto de una instalación en delta / sommet du triangle https://www.google.de/url?sa=t&rct=j&q=&esrc=s&source=web&cd...

As it is not clear from the context, what grid system is used, the alternate interpretation is also possible: Area Generation, transmission and distribution of electricity - General / Equipment IEV ref 601-03-09 en phase the designation of any conductor, bundle of conductors, terminal, winding or any other element of a polyphase system, which is intended to be energized under normal use fr phase, f désignation d'un conducteur, d'un faisceau de conducteurs, de bornes, d'enroulements ou de tout autre élément d'un réseau polyphasé et susceptible d'être sous tension en service normal http://www.electropedia.org/iev/iev.nsf/display?openform&iev... Area Generation, transmission and distribution of electricity - General / Equipment IEV ref 601-03-03 en electric line an arrangement of conductors, insulating materials and accessories for transferring electricity between two points of a system fr ligne électrique, f ensemble constitué de conducteurs, d'isolants et d'accessoires destiné au transfert d'énergie électrique d'un point à un autre d'un réseau http://www.electropedia.org/iev/iev.nsf/display?openform&iev... A three-phase system may be arranged in delta (∆) or star (Y) (also denoted as wye in some areas). A wye system allows the use of two different voltages from all three phases, such as a 230/400 V system which provides 230 V between the neutral (centre hub) and any one of the phases, and 400 V across any two phases https://en.wikipedia.org/wiki/Three-phase Area Generation, transmission and distribution of electricity - General / System configuration IEV ref 601-02-03 en three-phase system diagram a diagram of a three-phase system in which all phase and neutral conductors are each represented by separate lines fr schéma triphasé d'un réseau, m schéma d'un réseau triphasé dans lequel chaque conducteur de phase et de neutre est représenté http://www.electropedia.org/iev/iev.nsf/display?openform&iev... Area Power transformers and reactors / Connections IEV ref 421-10-01 en star connection Y connection (US) wye connection (US) the winding connection so arranged that one end of each of the phase windings of a polyphase transformer or reactor, or of each of the windings for the same rated voltage of single-phase transformers or reactors associated in a polyphase bank, is connected to a common point, i.e. the neutral point, and the other end to its appropriate line terminal fr connexion étoile, f connexion des enroulements dans laquelle une extrémité de chaque enroulement de phase d'un transformateur ou d'une bobine d'inductance polyphasés ou de chaque enroulement de même tension assignée pour les transformateurs ou les bobines d'inductance monophasés constituant un groupe polyphasé, est connectée à un point commun, le point neutre, l'autre extrémité étant reliée à la borne de ligne correspondante http://www.electropedia.org/iev/iev.nsf/display?openform&iev... Anyway, I wouldn’t use "line" or "ligne", as this term is specific for transmission lines: Area Electrical and magnetic devices / Connections and connecting devices IEV ref 151-12-27 en line device connecting two points for the purpose of conveying electromagnetic energy between them Note 1 – Electromagnetic energy may be extracted from or supplied to a line at an intermediate point.

Note 2 – Des exemples de lignes sont une ligne bifilaire, une ligne polyphasée, une ligne coaxiale, un guide d'ondes. http://www.electropedia.org/iev/iev.nsf/display?openform&iev... -------------------------------------------------- Note added at 2 days20 hrs (2017-08-23 07:23:57 GMT) -------------------------------------------------- Excerpt from ELECTRICAL CURRENT ABROAD, 1984 Edition: Alternating nominal voltage: Alternating current is normally distributed either through 3 phase wye ("star") or delta ("triangle"), 4-wire secondary distribution systems. In the wye or star distribution system the nominal voltage examples are: 120/208, 127/22, 220/380, and 230/400. The higher voltage is 1.732 (the square root of 3) times the lower voltage. In a delta or triangle system, 110/220 and 230/460 are examples of nominal voltages. The higher voltage is always double the lower voltage. The higher voltage is obtained by using 2 or 3 phase wires and the neutral wire while the lower voltage is the voltage between the neutral wire and one phase wire. The higher voltage may be single or 3 phase while the lower voltage is always single phase and used primarily for lighting and for small appliances. https://babel.hathitrust.org/cgi/pt?id=uc1.b4263653;view=1up... Electric Current Abroad A useful tool for exporters, manufacturers, and travellers alike, “Electric Current Abroad” lists the characteristics of electric current available and the type of attachment plugs used in over 150 countries. It is an update of a similar handbook published in 1991. The booklet includes a comprehensive table that indicates the type of current (alternating or direct current), number of phases, frequency (hertz), and voltage, as well as the stability of the frequency and the number of wires to a commercial or residential installation. http://www.trade.gov/publications/abstracts/electric-current... As shown above, the generic term for any "leg" is "phase", "phase" in French as well. |
