Yes, the Long AC lines from remote generators tend to be unstable, and ?was a real big problem for AC. I tell mechanical people it is like having a motor driving a mile long shaft with a wood chipper on? the end, even if there were bearings every 2 feet.. but I have not seen one. ? toggle quoted message Show quoted text From: [email protected] [mailto:[email protected]] On Behalf Of Mike Langner Sent: Wednesday, July 31, 2024 4:13 PM To: [email protected] Subject: Re: [HallicraftersRadios] S-38B Tuning Shaft Query ? Yes – because DC has no “crest factor,” it makes greater efficient use of transmission.? The peak, average, and RMS values for DC are all the same, reducing insulation requirements and eliminating the periods of the AC wave where the instantaneous RMS current is more than the time-averaged RMS current. As we remember I squared R is the formula for loss, so less loss, less heat, smaller conductors, and cheaper insulators! Plus – no synchronization problems!! Interesting return to Edison’s original idea – but without the DC generators he had hoped to see every few blocks in cities, and to homes in rural areas! Mike/ K5MGR -- don??? va3drl
