CYECT1-110D Electronic Current Transformer

Product Overview

The products accord with standard IEC60044-8 , IEC61850-9 ,GB/T20840.8-2007, digital output can expediently match with electric instrument, digital measure and protective equipment, and can meet customer’s other special requirement.

Feature

• High-precision measurement: Capable of accurately sensing and converting current in 110kV lines, with the output signal being highly proportional to the primary current and stable phase difference, meeting strict metering and monitoring standards.

• Strong anti-interference ability: Adopts optical fiber for signal transmission, achieving complete electrical isolation between the high-voltage circuit and the secondary circuit, avoiding electromagnetic interference, and ensuring stable and reliable data transmission.

• Wide frequency response: The electronic circuit design enables it to measure large currents and DC currents, breaking through the limitations of electromagnetic transformers and adapting to complex current environments.

• Compact size and light weight: Compared with traditional transformers, it has a compact structure, facilitating installation and deployment in substations or power equipment with limited space.

• Excellent environmental adaptability: Moisture-proof, dust-proof, and impact-resistant, it can operate continuously and stably in harsh outdoor or complex industrial environments, ensuring the stability of the power system.
