48 - Intro to 3 Phase Systems | Star and Delta Connection
In todays video, we shall discuss the introduction to three phase systems, the two modes of connection - star and delta, and the relationship between the phase and line voltages and current and so on.
A three phase system is a system or circuit produced by a generator consisting of three sources with the same amplitude and frequency but out of phase with each other by 120.
V1 = V sin wt
V2 = V sin wt - 120
V3 = V sin wt - 240 or +120
