Talk:Isolation transformer

From Wikipedia, the free encyclopedia

Dear sir please send me details of working of transformer isolated barrier.can i get the ckt diagram that how it will work ?please send urgently. regards Umesh

Ground Fault Isolation We are using 120V commercial grade electronic ballasts, properly grounded, rated at 2Amps to drive two low pressure UV lamps submerged in water rated at 800mA. System requirements are to use GFI barkers with each ballast. This installation in a wastewater treatment plant, where there are motors, pumps and air compressors. GFI’s are randomly tripping at 5mA from ballast electronic current leakage up to 9.2mA. Can we resolve our nuisance GFI tripping by using 120V to 120V isolation transformers between the GFI and electronic ballast?

You've probably got a defective ballast or defective GFCI breaker.

Wikipedia is not the place for such queries. I don't think that the bit of how-to information about connecting two power transformers symmetrically to create an isolation transformer belongs here either. Eikimart 19:58, 16 August 2007 (UTC)

[edit] Protecting Audio-Video equipment

How do we fully protect the home AV equipment in case of any possible problems in the mains power network (fluctuations, noise, etc)? I read that there are seven types of power problems. So how do we protect our consumer electronics against all these problems, without loosing quality in sound and video? I was informed about two solutions: 1/. On-line UPS or 2/. Isolation transformer and Power Conditioner. But these two solutions, as i was told, affect the quality of the sound. Does anyone know why this happens? What are the advantages and disadvantages of these two solutions? Why is the isolation transformer used in our case, how does it protect? Are there other solutions?
