In general I agree, with found parts generally being unreliable. In this case, I know some of the ones I received were uninstalled to do a conversion to new digital voltage regulators.
Got into the gen today, pulled all the diodes, tested them, all were good. Since I had the end bell off, went...
My question as well. No way to ever know for sure since I wasn't standing there when it was done. They did meg the field (F1 & F2) to ground, and the instructions include making sure those connections are lifted from the AVR prior to doing so. And these are guys I trust and they do it for...
I have a new problem with my power plant on the boat. Had some maintenance done, including insulation tests. Went to put a generator on the bus and it wasn't producing voltage. Suspected fuses on the VR3, and sure enough they were blown. Put new ones in, switched it into auto mode and saw it...
Been very busy but just wanted to follow up and say thanks for all the replies. I ended up putting in a new synchronizer and everything working great, also got my speed control problems fixed, just needed a little TLC on the linkage. Whoever did it before I got here had it set to max out on the...
Gotcha. That is something I can verify, whether my voltage coming from the 2301 is still the same when it reaches the plug to the governor actuator when it's switched into parallel. It wouldn't make sense to me to ever have this sent through anything else but who knows, i haven't found any...
Hey TugboatEng. As far as I'm aware the speed signal isn't sent through a switch or relay. It's just a single mag pickup that first terminates in the local control on the overspeed box and then splits off to the local rpm gauge, a remote rpm gauge and the 2301. Not a great design choice in my...
Thanks for the reply. I'm fairly in tune with how this plant runs and it's definitely something new occurring, a .5ish hz change is pretty noticeable on a meter with a span of 58 to 62.
In my past experience with other plants, like you described, put switch into parallel, adjust oncoming...
Have two 3306 caterpillar 175kw generators with 2301 speed and load share controls and spm a synchronizers for each. When one of the generators is online and holding the load and second generator is running at rated producing power but not on the bus I have an issue when attempting to parallel...
