It must be my explanation. We did that 2 out of the possible 6 configurations and both produced the same voltage. I had an electrician watch me and I sent you the drawing of how I connected it. I also had an engineer from a motor shop in Louisiana go over it with me just so I could say it out...
Sir . I UNDERSTAND!!! I restap with every storm or flood from NC to Florida and as far west as Texas. I'm measuring at the end of a 40" power generation cable. The neutral is tied to the said neutral bar. This gen was L1-N 208 and L2-N 120. 240 L-L. An engineer at a rewind shop explained to me...
No sir. The 4 neutral leads landed on an isolated neutral bar in the electrical cabinet. The four leads that were isolated were tied up wrapped in splice tape, abrasive wrap, and covered with super 88. The voltage was still 208 L1-N and 120 L2-N. If you look at the picture I attached on 10/31...
After a 2 hour load bank test, my load was balanced and my voltage was stable throughout the test. My windings were almost ambient tempature at 80% load. I started out not knowing the start and stop wires on each winding. I had no way to see that with the equipment I have. I have probably...
PROBLEM SOLVED!! I prayed and flipped the last group over. L1-N 120, L2-N 120, L1-L2 240. The orientation of the windings came from interposing nema numbers over my only " "known good" configuration. I guess there was still a bit of difference is why I got the odd voltage. I strapped it DD as...
My neutral connection for my load should still be 8,6,2,10 right? Tape up 9,1,3,11 right? That's what I have L3-N is 208. L1-N is 120. If I measure from mt tie up point (1,9,3,11) it just moves my 208 to L1-N. Am I still not understanding?
I have moved the neutrals to another phase but my result is 120 L-N and 208 L-N. 240 L-L. Before this I used 2 other zigzag configurations with the same results. The 208 is always the result. ???
My original connection was:
L1- 7,5
L2-1,9
L3- 4,12
N- 3,8,6,10,2,11
Again though this looks off my windings are:
1,2
3,4
5,6
7,8
9,10
11,12
I chose L3 because of my wire routing. I took 3,11 and connected to 1,9 which was L2. I got 240 L-L. L1-N- 120. L2-N was 208. Was my choice of connection...
In this their any disadvantage or loss to this configuration? Is it more or less efficient than a double delta? Is your recommended connection considered a zigzag configuration?
Thanks for the connection instruction. My drawing and data plate was too much data to attach. So I wrote my winding numbers along with the model and serial at the bottom of the page. When you say double wye you are talking about what I call parallel wye. So starting with that I change a few...
I am working on an older Generac generator for a customer who is going to use this unit in a different application. The voltage is 208/120 parallel wye. I am going to change it to 240/120 double delta. The gen is a 1998 trailer unit and I have not found any resources on a reconfiguration for...
