Norma Iec 61869-2 Jun 2026

Designated as 0.1, 0.2, 0.2S, 0.5, 0.5S, 1, 3, and 5 .

is the specific part of this series titled: “Additional requirements for current transformers.” It acts as a supplement to IEC 61869-1 (General requirements) , meaning it does not repeat general definitions found in Part 1 but focuses strictly on the unique characteristics of current transformers.

This duality ensures that a single substation can simultaneously perform accurate billing measurement and reliable fault detection using different CTs on the same power line. norma iec 61869-2

The primary voltage range is not a limiting factor; instead, the standard focuses on the transformer's rated primary current, its accuracy class, and its intended application—whether for precise revenue metering or robust fault protection.

The standard specifies standard values of rated burden (e.g., 1.5, 3, 5, 7.5, 10, 15, 30 VA) at a rated power factor (typically 0.8 lagging for metering, 1.0 for protection). A CT must maintain its accuracy within these specified burdens. Designated as 0

For metering cores, the standard defines the . This limits the secondary output during a fault to prevent damage to connected metering instruments (which are not designed to handle high fault currents).
