A transformer can not act as a phase changing device and change single-phase into three-phase or three-phase into single phase. To make the transformer connections compatible with three-phase supplies we need to connect them together in a particular way to form a . ConverterTransformer. Gassing and Failures. Similar transformers not gassing or failing. Increased harmonic currents. No gassing during factory load run. No increase in gassing during 2 day Field test load run. an. Instrument Transformer ?: .
