The forgotten properties of Isolation Transformers

Designed specifically for applications where harmonic currents are the rule, the Admagnetics Isolation Transformer has a number of fundamental features that are not always apparent. Over time these features appear to become overlooked. The first of these features is the Dzn0 connection. The primary winding being a conventional delta connection whilst the secondary connection is an inter-connected star, more commonly referred to as a zig-zag connection. The importance of this zig-zag connection lies in its ability to cancel the balanced portion of triplen harmonics within the secondary winding.
