Effect of the Conductor Positioning on Low-Power Current Transformers: Inputs for the Next IEC 61869-10

none3noLow-power instrument transformers (LPITs) are spreading among the distribution net- work thanks to their features (e.g., compactness, lightness, enhanced bandwidth, etc.). It is then a fundamental to guide users and manufacturers to a correct usage and manufacturing of the LPITs. Technical committees, which are in charge of writing dedicated standards, often tackle such a task. Focusing on the current type of LPITs, the low-power current transformers (LPCTs), the associated standard is the IEC 61869-10, which is going to be improved in 2021. To this purpose, the work aims at providing new inputs for the future version of such a standard. In particular, the focus is pointed towards the effects of the conductor positioning on the window-type LPCT accuracy. Literature and gained experience in the field are the two pillars that have been used to refine the outcomes of the work, which are provided in terms of suggestions for each technical aspect, as discussed in the standard, related to LPCTs.openMingotti, Alessandro; Peretto, Lorenzo; Tinarelli, RobertoMingotti, Alessandro; Peretto, Lorenzo; Tinarelli, Robert
