IEC 61869-15:2018 PDF

Scope: This part of IEC 61869 provides all requirements specific to voltage transformers to be used in DC applications (DCVTs), whatever the technology used. The output signal can be analogue or digital. It is applicable to newly manufactured voltage transformers used for measuring, protection and/or control applications in DC power systems with a rated voltage above 1,5 kV. This document covers passive voltage dividers as well as active voltage transformers, used for measurement, control and protection. The general configuration of a single-pole low-power instrument transformer is described in Figure 601 of IEC 61869-6:2016.
