The problem with switching transformer primaries with triacs is
the high inrush current that can develop. For example, if the
transformer magnetizing flux is strongly of one polarity when
it's turned off, and the ac line is pushing toward the peak of
the other polarity when the triac is turned on, the transformer
core will saturate and the primary will look like a section of
thick copper wire across the AC line. Very high currents will
flow for a portion of an ac cycle. Your triac is designed to
handle a little of this, but it's highly stressful and should
be minimized.


There are several solutions, including zero-crossing switching,


** How ****ing ASININE of *Winnie * the posturing pommy **** head !!

Any competent person knows that " zero switching " the AC main supply
*guarantees* consecutive maximum inrush current surges into a supply
transformer.

Is the vile puke really completely ignorant of simple physics involved ?

I hope the slimy **** chokes.
