Re: [TCML] GFI Transformer Help



Matt,

Sounds like you have a modern solid state inverter unit, which is unsuited for TC work. The GFI units in question are small circuit boards tucked in along with big heavy iron core NSTs in steel cases filled with asphalt or epoxy with large insulators on the ends. By dissecting out the connections to this board, some experimenters have been able to identify the power input leads and the connections to the transformer primaries. These may be reconnected judiciously to bypass the GFI functionality. In the solid state inverter units, the GFI function is integrated into the control electronics (likely a custom microcontroller), and is unlikely to be circumvented.

convention all week. My transformer is a smallish, light weight, black box
that is mostly empty when you take the cover off. There is a part inside
that is encased in white epoxy looking stuff. Is that the GFI?
