Split-phase electric power (original) (raw)
Ein Einphasen-Dreileiternetz (englisch split-phase electric power) ist ein Stromversorgungs-System, das üblicherweise in Nordamerika für Einfamilien-Haushalte und Kleinbetriebe (bis etwa 100 kW) verwendet wird. Es ist die Wechselstrom-Variante von Edisons mittlerweile historischem Dreileiter-Gleichspannungs-System. Da auf zwei Leitern Spannung anliegt, wird es oftmals irrtümlich als „Zweiphasenstrom-System“ bezeichnet. Tatsächlich liegen an beiden Leitern jedoch lediglich gegenphasige (180° zueinander) Wechselspannungen an.

Es ist die Wechselstrom-Variante von Edisons mittlerweile historischem Dreileiter-Gleichspannungs-System.

Tatsächlich liegen an beiden Leitern jedoch lediglich gegenphasige (180° zueinander) Wechselspannungen an. (de) Un sistema de corriente de fase partida o fase dividida (en inglés split phase) es aquel que consta de dos corrientes alternas monofásicas distribuidas en 3 cables o hilos, se usa normalmente en Estados Unidos en viviendas unifamiliares y pequeños comercios. Es el equivalente, en corriente alterna, al original sistema de corriente continua Edison de tres hilos. Para evitar confusiones con el motor eléctrico de fase partida, es aconsejable denominar a este sistema de voltaje como sistema de fase única de 3 cables. (es) A split-phase or single-phase three-wire system is a type of single-phase electric power distribution. It is the alternating current (AC) equivalent of the original Edison Machine Works three-wire direct-current system. Its primary advantage is that, for a given capacity of a distribution system, it saves conductor material over a single-ended single-phase system, while only requiring a single phase on the supply side of the distribution transformer. This system is common in North America for residential and light commercial applications. Two 120 V AC lines are supplied to the premises that are out of phase by 180 degrees with each other (when both measured with respect to the neutral), along with a common neutral. The neutral conductor is connected to ground at the transformer center tap. Circuits for lighting and small appliance power outlets (i.e., NEMA 1 and NEMA 5) use 120 V circuits - these are connected between one of the lines and neutral using a single-pole circuit breaker. High-demand applications, such as ovens, are often powered using 240 V AC circuits - these are connected between the two 120 V AC lines. These 240 V loads are either hard-wired or use NEMA 10 or NEMA 14 outlets which are deliberately incompatible with the 120 V outlets. Other applications of a split-phase power system are used to reduce the electric shock hazard or to reduce electromagnetic noise. (en) 単相3線式（たんそうさんせんしき）とは、「単三」「単3」とも略称され、単相交流電力を3本の電線・ケーブルを用いて供給する低圧配電方式。 (ja) Een gesplitstefasesysteem of enkelfasig driedraadssysteem is een type eenfasig elektriciteitsnetwerk. Dit systeem is gebruikelijk in Noord-Amerika voor residentiële toepassingen. Er zijn hier twee wisselstroomlijnen beschikbaar die 180 graden uit fase zijn met elkaar, met een gemeenschappelijke nulleider. De nulleider is verbonden met aarde en de middenaftakking van de transformator. (nl) |
