Title: How to reduce leakage current by design for medical grade toroidal transformer
Post by: yoganand on December 13, 2012, 11:38:53 am
Hi all,

I need to design low leakage current for medical grade transformer. If anybody in the loop pls help me.
Transformer specification : Primary 120V/60Hz, Secondary 120V/1000VA....leakage current < 50µA...Advance thanks for your help.

Low leakage here presumably means SAFETY FIRST.
So why are you asking on a public forum where any idiot, such as myself, can give you a silly answer?

In the wrong section, with only one post?

Because the primary and secondary are the same voltage I assume it's an isolation transformer..
