Many people familiar with HV protection schematics and wiring will be aware of the different wire numbering on CTs but may not know why it is used or what guidelines are followed for labelling. They are often simply copied from sheet to sheet without proper checks or understanding.

The Iron core and windings play a key role in defining the characteristics of a transformer. There are a number of different transformer shapes available.

In May I headed off to Northern China for a week to do QA inspections on a large transformer project. The weather was definitely warming up and I noticed a lot of changes since my last visit only a few months previous.

Amorphous core transformers are manufactured using ferromagnetic amorphous metal formed into thin foils. Their higher resistance and thinner foils have been proven to lead to low losses and better resistance to harmonic wave. The use of amorphous metal transformers gradually gained popularity, particularly throughout India and China who have been using them since about 2005. Europe and the USA have been slightly more cautious to use this type of transformer, due in part to the higher labour costs of production.
