In the realm of electrical engineering, the accurate measurement of current is fundamental to the safe and efficient operation of power systems. Whether for metering energy consumption or protecting grid infrastructure from faults, Current Transformers (CTs) are the unsung heroes of the substation. The international standard that governs the accuracy, safety, and testing of these crucial devices is .

The transition to IEC 61869-2 represents a shift toward digitalization in the power grid. By accommodating Low-Power CTs and digital interfaces within the same standard framework as traditional inductive CTs, the IEC has future-proofed the industry. In the realm of electrical engineering, the accurate
IEC 61869-2 is a specific part of the overarching IEC 61869 series, which replaced the older IEC 60044 family. The standard applies to newly manufactured inductive current transformers intended for use with electrical measuring instruments and protective devices operating at frequencies from 15 Hz to 100 Hz. It is crucial to note that this standard explicitly covers inductive CTs—the conventional iron-core type—while other parts of the series address low-power, electronic, or other specialized transformers.
