Operating men find in Carton-Daniels D. C. lightning arrestersthe same principles that are embodied in the A. C. Types—the com-bination of small air gap distance, low series resistance and a positiveelectrically operated circuit breaker. Small air gap distance means efficient protection ; low series resist-ance means the elimination of heavy current flows to ground thatotherwise would follow the lightning discharge, hence the eliminationof low voltages, severe strains on the windings of the generatingequipment, and other evils, the circuit breaker gives a positive cut-off of this flow to ground and so eliminates the gro
