Such a systemwould constitute a three-phase six-mre system. The three circuits connected to the differ-Bnt phases may be kept practically independent of eachDther by using lour leads and connecting three of the col-ector rings together, as shown in Fig. 299. The lead (4)serves as a common return to… … Fig. 296 [ 362 PRACTICAL APPLIED ELECTRICITY circuits are equal and displaced in phase from their electro-motive forces by the same angle, the three currents are then120 degrees apart and their vector sum, which is the currentin main (4), is zero. Hence, for a balance load, main (4)carries no…
