Re: The Beginnings of a Fusor Electrical System

So, after ordering some more alligator leads, I ran a test on my fusor. I had imperceptible voltages across all points with backwards wiring. I switched my measuring lead to be on 3 and 4, and turned my variac down to under 5 volts, put my inputs on pins 5 and 6, and turned the input on. The output ...

Re: The Beginnings of a Fusor Electrical System

I feel that I first have to apologize for any perception of my ability as inadequate or lacking, as most of the time it seems to be my incoherency or unclear explanations that lead to these situations. This is my attempt to clarify my goals and what I know and don't know. I'll first explain how I ap...

Re: The Beginnings of a Fusor Electrical System

So, I finally acquired all of the components necessary to test my supply. I've spent the last few months working, and I've bought the components I believe will enable me to reach the demo phase. So, what I'll do in this post is verify my plan and pose a few questions I have. The main question I hold...

Re: The Beginnings of a Fusor Electrical System

Quick question: I would use the full-wave rectification circuits for single-phase 120V 60hz input (standard mains electricity), grounding the positive load-end and using the negative rectified polarity with the instructional circuit seen in the schematic included? Not 100% sure, and I don't want to ...

Re: The Beginnings of a Fusor Electrical System

Thanks for your response, Rich. I did mean the voltage increase when I said power. Sorry for that careless mistake. I do have a guy, Matt D. who works at the local coal power plant who has helped me in the past and will likely help me with the overall system (i.e. grounding, other things specific to...

Re: The Beginnings of a Fusor Electrical System

Would the next step be to variac the primary way down and see what the ratio of power increase is? Or is there more still to learn before I plug it in?

Re: The Beginnings of a Fusor Electrical System

Rich-
Please correct me if I'm wrong, but this is the calculation I did to get the values.
For the coil with a resistance of 160K ohms at .02A, voltage drop is derived from V=IR, so V=. 02*160000,so V=3200V. Power Dissipation is P=IV, so P=.02*3200, so P= 64A.

Re: The Beginnings of a Fusor Electrical System

I've worked to identify the wires on the transformer. The x-y table of the resistances is listed below, and I've laid out the separate networks in a drawing labeled with the resistances.

Re: The Beginnings of a Fusor Electrical System

So, I've measured 0 on everything but point 2 at the battery voltage in respect to point 4, and 0 on everything except for a 7.5V reading on point 2 in respect to 8. In respect to point 1, there are -6.6V on point 4 and -7.6V on either 8 and 10.

Re: The Beginnings of a Fusor Electrical System

Mr. Feldman I do have some considerable experience with low voltage electrics (Arduino, Tesla coils, etc). I had that exact electricity kit as a kid. Good stuff. I apologize for having led you to believe my lack of experience; I simply would like to exercise extreme caution in this process. Your ori...
