Introduction to Three Phase Power http://www2.tech.purdue.edu    See how three phase power is produced. A step by step presentation that enlighten us on the true underlying principles in the operation of a three phase power. Three Phase http://en.wikipedia.org   In electrical engineering, three-phase electric power systems have at least three conductors carrying voltage waveforms that are 2π⁄3 radians (120°, 1⁄3 of a cycle) offset in time. In this article angles will be measured in radians except where otherwise stated. Review of Three Phase Circuits http://www.eece.ksu.edu   Following are the requirements that must be satisified in order for a 3-phase system or circuit to be balanced All 3 sources are reprensented by a set of balanced 3-phase variables All loads are 3-phase with equal impedances Line impedances are equal in all 3 phases Having a balanced circuit allows for simplified analysis of the 3-phase circuit. In fact, if the circuit is balanced, we can...
