EMR4-A400-1 überwacht Drehstromnetze
auf Asymmetrie der Phasen, Phasenfolge
und Phasenausfall auch bei 95 %iger
Regenerierung dieser Phase.
Bei 2-phasig weiterlaufenden Motoren kann unter
Umständen soviel Rückspannung erzeugt werden
(> 95 %), dass das Ausgangsrelais trotz Ausfall einer
Phase nicht abfallen kann.
EMR4-A400-1 monitors three-phase systems for phase
asymmetry, phase sequence and phase failure, also
with 95 % phase regeneration.
With motors that run on with two phases, the reverse
voltage generated can be so high that the output
relay is unable to drop out even in the event of a
phase failure.
L’EMR4-A400-1 surveille les réseaux triphasés pour
détecter l’asymétrie des phases, la suite des phases et
les défaillances de phase même avec une régénération
de 95 % de cette phase.
Dans le cas de moteurs à suite de fonctionnement
biphasée, il peut dans certaines circonstances se
produire une tension de retour telle que le relais de
sortie ne puisse pas retomber malgré la défaillance
d’une phase.
L’apparecchio EMR4-A400-1 viene impiegato in reti
trifase per sorvegliare l’asimmetria delle fasi, la
sequenza delle fasi e la mancanza di tensione su una
fase anche per una rigenerazione del 95 % di tale fase.
Nei motori che continuano a funzionare con
alimentazione bifase, in alcuni casi può essere generato
un valore di tensione indotta (> 95 %) tale per cui il
relè di uscita non può diseccitarsi nonostante la
mancanza di tensione su una fase.
EMR4-A400-1 vigila en redes trifásicas la asimetría
de las fases, la secuencia equivocada de fases y el
fallo de fase aun con un 95 % de regeneración de
esta fase.
En caso des motores que siguen funcionando en dos
fases, circunstancialmente se puede generar una
tensión inversa suficiente para que el relé de salida
no se pueda desexcitar a pesar de haber fallado una
fase.
