“…M open core allows the primary winding t serially connected sections which are com the natural oil flow, as well as the co capacitively graded main insulation, whi order for transformers to comply with requi voltage levels. Furthermore, the capacitive main insulation are connected to the sectio winding, thus assuring a constant synergy leading to transformer insusceptibility towar different character and origin [4].

The Power Voltage Transformer, which is a singlephase unit used for direct conversion of power from high to low voltage, is becoming more and more relevant for substation application. This is why this paper aims to present the properties and advantages of the open-core design concept, which has been functioning very well for a number of years in inductive voltage and combined instrument transformers, enhancing the transformer reliability and operational safety. Furthermore, the intention is to list the known possible application options of these transformers and finally to succinctly point out the guidelines for future development, which would benefit both the manufacturer and the user.
