And I maintain that just because some GOSS is wound into a spiral,
the U compared to an interleaved E&I tranny won't necessarily be
10 to 15 times what it is in the E&I lams.
** Two counter examples:
#1.
The I mag @ 240 volts for a 300 VA mains toroidal ( from Harbuch) on
the
bench is 11mA rms.
At 120 volts, I mag falls to 1.7 mA, becomes sine wave and has a 12
degree
phase angle.
The load R is effectively 70 kohms.
For this case, L computes to be over 1000 H using: L = R / (
2.pi.50.
tan 12d )
#2.
The I mag @ 240 volts for a 160 VA mains toroidal ( from Jaycar) on
the
bench is 7 mA rms.
At 120 volts, the I mag falls to 1.6 mA, becomes near sine wave and
has a
15
degree phase angle.
The load R is effectively 75 kohms.
L computes to be nearly 900 H.
You are quite right with all these calcs
** Now you do the same for E -core tannies of similar ratings - your
own
or commercial ones.
Lets compares the I mag and effective L primary figures.
Lets see if the toroidals win by 10 to 15 times.
If you want to convince us any old toroid has 15 times the inductance
for an E&I tranny using the same material and with the same Bmax, you
better get on and do it,
** I just posted the bloody evidence - you ****ing brain dead ****.
Do similar tests using similar sized E cores and post the figures.
The I mag figures will reveal the effective inductance values being
achieved.
Failure to reply PROVES you are a lying, POS, autistic ****.
I think Phil, that you will find wrapping your head in tin foil will
keep down the chances of aliens trying to 'mind meld' you with their
arse-holes.
keep taking the tablets.
you're getting out of hand.
