Ive taken one of the stacked toroids off which was thermally damaged (they
get very brittle), now left with two. Ive replaced the primary (18 turns
#12 insulated )and secondary windings and back on at 49.5A loop current at
0220z Tuesday.
Taking temperatures with the thermal "imager" to check for further
hotspots.....
Ive learnt that microbore isnt too good in my application. Ive replaced the
2 turns secondary in series with C and the loop with #4 insulated cable and
seen a slight an increase of 3 amps in the loop current. The wind is blowing
a bit and storms are forecasted tomorrow.
