The problem is that zero sequence current from nonlinear loads, primarily third harmonic, will add up arithmetically and return on the neutral.
El problema es que la corriente de secuencia cero de las cargas no lineales, principalmente del tercer armónico, se sumará aritméticamente y volverá al neutro.
The ELCB is current electronic current leakage circuit breaker, the main parts include zero sequence current transformer, electronic panel, current leakage release and the circuit breaker with protection functions of over load, short circuit.
El ELCB es disyuntor actual electrónico actual de la salida, las piezas principales incluye el transformador corriente de la secuencia cero, el panel electrónico, la liberación actual de la salida y el disyuntor con funciones de la protección de la carga excesiva, cortocircuito.
This is obtained through elimination of the zero sequence current by selecting a suitable vector group or through direct numerical elimination of the zero sequence current.
In three-phase four-wires low-voltage systems, the effects of current harmonic currents can be even worse, if compared with three-wire networks with no neutral conductor, as an additional zero sequence current, produced by single-phase distorting loads, flows through the neutral wire.
En redes de baja tensión con neutro, este problema todavía se agrava más a causa de las cargas distorsionantes monofásicas, cuyas corrientes homopolares se suman en el conductor de retorno.
