High-Accuracy Current Transformers for Power Distribution & Metering

Current transformers (CTs) are the backbone of modern power measurement and protection systems. For utilities, electrical contractors and industrial facilities across Europe and North America, selecting the right current transformer directly determines metering accuracy, protection reliability and long-term operational safety. Our high-accuracy current transformers are engineered to meet the rigorous requirements of IEC 61869 and ANSI/IEEE standards, delivering consistent performance in demanding grid and industrial environments.

Project Background

A leading European electrical equipment distributor needed a dependable current transformer solution to support a series of power distribution and smart-metering projects across multiple regions. The client required transformers that could deliver stable measurement accuracy under varying load conditions, while also meeting strict safety and compliance standards for the European market.

Solution Delivered

We supplied a comprehensive range of low-voltage and medium-voltage current transformers, including wound-type, window-type and bushing-type models, tailored to the client's specific ratio, accuracy class and burden requirements. Each unit was manufactured with high-permeability silicon steel cores and precision-wound secondary windings to ensure consistent accuracy across the full operating range.

Key Product Features

• Accuracy classes from 0.1 to 0.5, suitable for revenue metering and protection
• Wide primary current range from 5A to 5000A to cover diverse applications
• Compact, flame-retardant enclosure meeting UL 94 V-0 requirements
• Full compliance with IEC 61869-2, ANSI C57.13 and relevant EU directives
• Customizable ratios, mounting styles and terminal configurations
