Three Phase Electricity Basics and Calculations electrical engineering

Three Phase Electricity Basics and Calculations electrical engineering



In this video we learn how three phase electricity works from the basics. We explain how three phase electricity is generated, how the voltages vary, how to calculate the voltages and vrms, what frequency, hertz and cycle mean and how we get two different voltages from a three phase supply. We look at wye and delta, transformers and generators. We start with a simple single phase AC generator and then add in a second and third phase to under stand its working principle.
