This guide gives you the technical backbone for working with IEC 61869-2 CTs. If you need a deeper dive into one section – e.g., transient performance of TPY vs TPZ, or burden mismatch calculation – just ask.
The standard modernizes the approach to sensors. It accommodates electronic current transformers (ECTs) and low-power iron-core CTs (output in mV or digital signals), paving the way for IEC 61850 and digital substations. iec 61869 2 current transformers
is part of the IEC 61869 series (“Instrument Transformers”). It supersedes the old IEC 60044-1 standard. This guide gives you the technical backbone for
