Electrical Engineering: Ch 13: 3 Phase Circuit (41 of 53) Finding the Current Needed
Показать описание
In this video I will find line-current needed=? for a 25kW 3-phase motor with a power factor of 0.80 when connected to a balanced 220V source. This will require using the triangle representing the real power, P; the reactive power, Q; and the complex (apparent) power, S. And the relationship where the complex power, S, is a function of the line-voltage and line-current.
