There is another method of coupling up thefield coils. This is shown in Fig. 113, and is called STAR AND LINK COUPLING. 343 link coupling. In this system there is no electricalcentre which can be earthed, but the coils are connectedto form a triangle or closed link, tapped by the linewires in three… … moment when one current, say a, passes through zero,the other two, b and c, produce an excitation of 1*3 Itampfere -turns, whilst a twelfth of a period later, when bis a maximum and a and c have half the maximumvalue, the excitation is /1. The fluctuation of excitingpower is thus considerably…
