Hello there,
I am working with a transformer to take 230VAC to 18.8VAC for the first time. I am super-careful, and have placed the transformer in a plastic box, with only the leads coming out.
I connected CH1 to transformer output (18.8VAC) and CH2 and to the rectifier output (16.6VDC). I wanted to compare the voltage from before and after rectification. I could tell something was wrong because the fuse on transformer input blew (1A). And all the leads and gear were current had been flowing was very hot. The waveforms on the scope didn't look like they were supposed to.
The question is, do you think it is safe to continue using the transformer? Is it likely that the insulation is so away so that it poses a risk for years to come? The transformer was hot, perhaps 50*C, but its had to say what temperature the windings may have been. What are your thoughts? Thanks!
