Re: Fw: Arc Impedance Study - Computer Models



Hi John,
    If memory serves, 10 kV.  The break rate was determined by the
natural break rate of the gap.

+AD4APAA8- +AD4-    In 1998 such a system was demonstrated at the
University of
+AD4- +AD4-Maryland Physics lecture hall.  The primary consisted of 2 turns of
+AD4- +AD4-2-0 welding cable wound directly around the secondary at its base
(6
+AD4- +AD4-inches by 27 inches, number 18 magnet wire, 5 inch by 20 inch
toroid).
+AD4- +AD4-The spark gap consisted of 3 gaps with 3 inch elkonite hemispheres
+AD4- +AD4-about 0.2 inches separation.  They were mounted on 4 inch aluminum
+AD4- +AD4-plates for heat dissipation.  The capacitance was about 0.1 uF
(mica
+AD4- +AD4-red RF capacitors shaped like bricks).  The primary power was about
2
+AD4- +AD4-kilowatts.  The secondary spark length was about 7 to 8 feet.  The
+AD4- +AD4-sparks were like nothing I have ever seen since.

+AD4-Barry,
+AD4-
+AD4-I wonder what voltage they were using?  High voltage with low break-
+AD4-rate, or very low voltage with higher break-rate?
