A three-phase system may be arranged in delta (∆) or star (Y). A wye system allows the use of two different voltages from all three phases, such as a 230/400 V system which provides 230 V between the neutral and any one of the phases, and 400 V across any two phases. A delta system arrangement provides only one voltage, but it has a greater redundancy as it may continue to operate normally with one of the three supply windings offline, albeit at 57.7% of total capacity. Harmonic current in the neutral may become very large if nonlinear loads are connected.","extract_html":"
