I assume that when you had zero potential accross the line between the 2 generators that is when you closed the breaker. How did you know whither the voltage waves were riseing or falling together before parralleing the machines
When I turned resistive load that was placed across the switch terminals, the current that would start to flow when the voltage started to go out of phase and that would hold the generators in phase long enough for me to close the switch thus locking them in phase together. I could have closed the switch without the resistive load but I was a little nervous to close the switch so I used the resistive load to act like a bungee cord "electricly" and to buy me more time to throw the switch.
I did use a Fluke model 78 series meter and a switch and a resistive load to synchronize the generators. I first adjusted the governors to match the engine speed as close as possible, then I used a cord with a male plug on each end and a switch in the hot lead breaking the connection between the two. I put my voltmeter across the switch contacts with the switch open, then I connected a 1500 watt resistive load across the open switch terminals and turned on the load when the phases matched.

How did you know exact moment of phases?
No way to catch it with a meter.
