1730 Polarity of neutral in WYE is unclear
Created: 28 Oct 2020
Status: Solution Accepted
Paragraph: CDC (WYE)
Figure 16 seems to request that Ineut = -(Ia + Ib + Ic). However in table 33, the definition of Ineut specifies the "algebraic sum of the instantaneous values of currents flowing through all live conductors."
61850 shall define un-ambiguously the Neut both for Current and Voltage systems, so that it is clear what is the interpretation of the associated samples, espcially when coming to the instrument transformer communication and process bus.
