    Heat Transfer thorugh Cable Insulation from a single source

    No. It's a calculation to support the experimentally proven fact that conductors running single phased in metallic conduit will melt the insulation. I left this out to try and keep my question simple as to not create a side discussion about the experiment itself, which will surely now happen...

    Heat Transfer thorugh Cable Insulation from a single source

    Hey all, I am trying to determine the heat flow into the insulation of an electrical cable with insulation from a heat source touching it at one point along its length. (Like a cylinder sitting on a hot slab) I am ignoring any convection at the moment. I have the equation: Q =...

    Eddy Currents Generated in a Ferrous Conduit

    Thanks for the response. Is it worth the time? Absolutely not. Unfortunately I have been tasked by my VP with trying to back up a field error that occurred and is being disputed. I am aware of the results as we validated them via experimentation.(And your right, it took about 20-30 minutes to...

    Eddy Currents Generated in a Ferrous Conduit

    Hey all, I'm looking for the equation/s to determine the heat energy created in a galvanized rigid steel conduit (10 inches long 3.5in diameter) The cables running through the conduit are 3 500MCM THHN Copper (all the same phase) at 1500A. Ultimately I am trying to take that heat energy and...
