I used to know and older engineer who worked with power systems. He'd be in his late 80's now. He explained the process they used to bring on-line a new generator. Connect a light bulb between the "hot" line of the generator and the utility power and adjust the phase and frequency until the bulb went out and stayed out, then throw the switch. not exactly high tech. I'd bet there are still places where this is what's used. -- ===== Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
