Re: Wet transformers....recovery?
Thanks Dr John. Once connected to the mains what 'ballpark' voltages should I be looking for? Obviously I can compare as I have more than one to test, but it would be good to know what should be expected.

Re: Wet transformers....recovery?
Hi Martin,
It is difficult to say due to all sorts of things but around +10/15% would be in the right area, if it is lower than the rated voltage, ie 5Vac should read a minimum of 5Vac no load, be very suspicious, probably shorted turns and also the magnetising current will be up. I will try to measure my magnetising current today to assist further. John aka Dr John |
