Re: TC measurements with LCR meter

to: Andy

Trying to accurately measure the Lp (pri inductance) is very difficult at
best).  We usually just measure the cap value and the resonant freq of
primary, and then calculate the pri inductance from the equation.  Much

Most LCR meters will measure the pri cap accurately and also your secondary
inductance.  Again, measure resonant freq of sec coil and then calculate the
distributed capacitance.

Also, see the archives for method to measure the coeff. of coupling, k.
This is very important for efficient operation and to prevent damage to your
primary components from kickback.
