But here is where the math breaks down... On my herd of 100KW RF generators... Every time the load failed for even a split second, those fire breathing dragons would blow a hole through the quarter inch thick slabs of copper that made up the line, instantaneously... The math didn't break down, Denny, your logic did. 1. The standing wave voltage is *ALWAYS* 90 degrees out of phase with the standing wave current, by definition. 2. It is *IMPOSSIBLE* to "blow a hole through the quarter inch thick slabs of copper" with a voltage and current that are 90 degrees out of phase. 3. Therefore, the voltage and current that blew the holes in the copper slabs were NOT 90 degrees out of phase and therefore were not standing waves. In-phase voltage and current is required to blow holes in copper slabs. 4. Standing waves are a steady-state phenomenon. Blowing holes in copper slabs is a transient phenomenon. At the end of steady-state, the standing wave energy is always converted into real watts and either radiated or dissipated. The energy that blew holes in your copper slabs did NOT meet the definition of "standing wave energy". During the transient state, it was converted from standing wave energy (with its 90 degree phase difference between voltage and current) to traveling wave energy (with its in-phase relationship between voltage and current). -- 73, Cecil http://www.w5dxp.com |
