Write short notes on 3 phase supply.
Answers
In electrical engineering, three-phase electric power systems have at least three conductors carrying alternating current voltages that are offset in time by one-third of the period. A three-phase system may be arranged in delta (∆) or star (Y) (also denoted as wye in some areas). 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 (centre hub) and any one of the phases, and 400 V across any two phases. A delta system arrangement only provides one voltage magnitude, 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.[1] Harmonic current in the neutral may become very large if nonlinear loads are connected.
Explanation:
- sonorous nature means that metals are generally sonorous and it also means that they produce sound when hit with solid object like bells are the most common example of that...
