Re: Magnetic quenching.

REACTIVE POWER IS NOT WATTAGE. Wattage is resistive power. You can calculate
the reactive power by compensating c or l to nulify the reactive factor. At
resonance your Xl and Xc are the same but oppisite so true power is I^2 R
not reactive. The apparent peek power is Xl^2I AND MAY BE MUCH NORE THAN
TRUE POWER. a 250 watt NST powered TC may have 400 amps and 20000 volts on
the primary. That is 8 meg watt of peek power in the reactive circuit, but
the real power in w/s is within the limits of the NST. Using a resistor in
the ground side of the secondary or in the primary of the NST will be close
to real power if properly compensated with line capacitors.
