(three-phase) three-module meter Explanation: three-phase meter Explanation: In general, I think this refers to three-phase circuits. My sources are not unequivocal. cccccccccc Jak działa licznik jednofazowy? Układ dwóch cewek (prądowej i napięciowej) wykonuje operację U*I*cosφ=P - moc czynna. Iloraz ten przekłada się proporcjonalnie na siłę działającą na tarczę, a dokładając jeszcze hamulec otrzymujemy prędkość obrotową tarczy proporcjonalną do siły, czyli mocy. Czyli moc P -> siła F -> prędkość n. W liczniku trójfazowym mamy trzy identyczne ustrojstwa, dla każdej fazy. Sumowanie mocy z poszczególnych faz polega na sumowaniu sił. https://www.elektroda.pl/rtvforum/topic809164.html#4152275 Definition: The meter which is used for measuring the power of three phase supply is known as the three phase energy meter. The three phase meter is constructed by connecting the two single phase meter through the shaft. The total energy is the sum of the reading of both the elements. https://circuitglobe.com/wp-content/uploads/2017/07/three-ph... https://circuitglobe.com/three-phase-energy-meter.html#:~:te... https://www.analog.com/-/media/analog/en/landing-pages/techn... https://www.analog.com/en/technical-articles/trends-in-three... Figure 3. Three-Phase Meter with Shunts, Separate Power Supplies, and Isolated Communication. ccccccc Main Service Modules ♦ Three module types - Main terminal box - Main circuit breaker - Main fusible switch. ♦ Mechanically and electrically built to bolt-up with the meter stack modules. ♦ 240V and 600V versions. ♦ 240V three phase main service modules can couple to both the 5 and 7 jaw 240V meter stack modules ♦ Three phase main service modules require three phase bussed meter stack modules for proper application. ♦ 240V Main service modules rated higher than 800A must be installed in a centre feed configuration when used with residential meter stack modules. When used with commercial meter stack modules they may be installed in a centre or end feed configuration. ♦ Type 3R enclosure (rainproof). ♦ All main service modules include both left and right horizontal bus closure plates.a ♦ For service entrance rating or grounding use GRDKIT ♦ Three phase feed through cable connection tap box available https://www.eaton.com/content/dam/eaton/products/low-voltage... |
