Iec61869-2 Now

IEC 61869-2 divides testing into three main categories to ensure product reliability and safety:

is the international standard governing additional requirements for inductive current transformers (CTs) used in electrical measuring instruments and protective devices . It serves as the primary replacement for the older IEC 60044-1 and IEC 60044-6 standards, consolidating requirements for both metering and protection CTs into one document. Core Structure & Relationship iec61869-2

: It specifies limits for ratio error and phase displacement across various classes (e.g., 0.1, 0.2, 0.5, 1, 3, and 5). IEC 61869-2 divides testing into three main categories

IEC 61869-2 is not just a renumbering. It is the international consensus for modern CTs. It addresses the reality of modern power systems (higher fault currents, more DC offset, digital interfaces, and smaller electronic relays).
