The power characteristics in polar coordinates, correspondingto the Figs. 196, 197, 202 and 203 are shown in Figs. 204, 205,206 and 207. The balanced quarter-phase and three-phase systems give aspolar characteristics concentric circles. CHAPTER XXXIINTERLINKED POLYPHASE SYSTEMS 283. In a polyphase system the different circuits of displacedphases, which constitute the system, may either be entirelyseparate and without electrical connection with each other, orthey may be connected with each other electrically, so that apart of the electrical conducto
