IEC EN 61869-2 Instrument Transformers - Additional Requirements for Current Transformers

EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of IEC EN 61869-2 testing. IEC EN 61869-2 applies to newly manufactured inductive current transformers for use with electrical measuring equipment or electrical protective devices with nominal frequencies from 15 Hz to 100 Hz. This International Standard is to be used in conjunction with and is based on IEC EN 61869-1.

This standard covers various current transformer specifications and test methods. The standard determines certain requirements in order to ensure the measurement accuracy of transformers, increase reliability and minimize measurement errors.

IEC EN 61869-2 covers various topics related to the design, testing and quality control of transformers. The standard also focuses on various technical features of transformers, including insulation, insulation, durability and safety features.

Standards generally focus on:

• Electrical Performance: Electrical performance properties of current transformers such as nominal current, linearity, phase errors are determined.
• Thermal Performance: How transformers behave under certain temperature conditions and their durability under these conditions are tested.
• Mechanical and Environmental Properties: Mechanical and environmental properties such as physical durability of transformers, protection classes and compliance with environmental conditions are determined.
• Insulation and Safety: Insulation levels, insulation properties and safety requirements of transformers are discussed.
