arc cir-cuits than any otherone type. It is simi-lar in principle to theblow-out arresterused on constant-potential circuits,except that the coilsare in series with thedynamo instead ofbeing connectedacross an auxiliaryair gap. The coils,therefore, carry the FlG- 5- current all the time the dynamo… … ELECTRIC LIGHTING. 19 blow-out coils, and unless they were of very low resistancethere would be considerable loss of energy. The air gap isbetween the vanes c, c. Fig. 6 shows how the arresters are con-nected. Current from the dynamo D flows through the coils Aand out on the line, thus setting up a…
