Hi all, I have a ign transformer taken from an oil burner. Its the type that send very high voltage to two electrodes causing an arc which ignites the fuel blown into the burner under pressure.
I have another use for it that involves it to be switched on but not arcing very often. I rigged it up like this and left it on but after about five hours it had overheated and burned out.
The draw in standby mode was if I remember only about fifteen watts. I have a pressure washer with one of these transformers which is always on and arcing and stays on for hours if I have a big job for the washer.
I expected the transformer to get warm but not hot enough to melt the insulation as it did and run all over the floor. I have a microwave transformer I tested last night and that works fine but I didnt want to leave it unattended in the garage all night as it might have been a fire risk if it did the same as the first one. I could immerse the transformer in oil in an open top container to cool it but I am not sure why it should get so hot when its just in standby mode.
I have the rest of today to switch it on and monitor it but dont want to leave it tonight. Any ideas?
