61869-2: En

By adhering to EN 61869-2, manufacturers can ensure their current transformers meet stringent quality and performance criteria, contributing to the overall reliability and efficiency of electrical power systems.

EN 61869-2 specifically focuses on current transformers, which are used to measure current in electrical power systems. The standard covers the requirements for the design, testing, and performance of current transformers, ensuring that they provide accurate and reliable measurements.

EN 61869-2 applies to newly manufactured current transformers (CTs) for use with electrical measuring instruments and protective devices at frequencies from 15 Hz to 100 Hz. It specifies the additional requirements that supplement the general standard EN 61869-1 (Common requirements). This includes definitions, ratings, design, testing, and accuracy classes. en 61869-2

Current transformers that comply with EN 61869-2 are used in a wide range of applications, including:

The standard ensures that current transformers: By adhering to EN 61869-2, manufacturers can ensure

The EN 61869-2 standard offers several benefits to users and manufacturers of current transformers:

Always specify CTs by referencing EN 61869-2 including accuracy class, rated burden, ALF (for protection), and FS (for metering). Avoid relying on superseded 60044-1 standards for new equipment.

Accuracy is typically guaranteed from 5% to 120% of the rated current.
