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 . current operating in outdoor or indoor conditionsThese instructions are valid for current transformer type TPO KOHU TPU IBZ IPZ ISZ IMT KOKU KODI IP 24where the ambient air is not signi31cantly pollut Hammond Power Solutions (HPS) is . a. leading manufacturer of dry-type transformers and related magnetics in North .
