# N-M18 Three-phase Circuits Module

## 創新系統

The Three-phase Circuits Module, "N-M18", designed by EDIBON, is used to study the generation of three-phase systems, load balancing between phases, operation of three-phase rectifiers, etc.

## 一般說明

Three-phase voltage is essentially a system of three alternating voltages, coupled (all 3 are produced simultaneously in a generator) and 120º out of phase with each other (i.e. one third of the period).

The Three-phase Circuits Module, "N-M18", designed by EDIBON, is used to study the generation of three-phase systems, load balancing between phases, operation of three-phase rectifiers, etc.

In addition, faults can be simulated in most of the circuits under study. The student must investigate what is happening in the circuit and why it is not working properly. These faults simulations can be of several types from damage components to a hypothetical incorrect circuit assembly.
