  • Single and Multi ratio options are available.
  • As per IEEE/ANSI C57.13 or IEC 61819-1 accuracy classes for metering and/or relaying
  • Wide range of windows and sizes
  • Wide range of ratios from 50:5 to 6000:5.
  • 1 Amp secondary available
  • Supplied with leads or terminals.
  • Custom secondary termination possible
  • Standard product range and custom solutions

Applications for Current Transformers:

  • Energy Management: CTs are extensively used in power metering and energy management systems to monitor electricity consumption accurately.

  • Protection Relays: In power distribution and transmission systems, CTs are employed with protective relays to detect faults and abnormal conditions, enabling swift and automatic responses to prevent damage or outages.

  • Industrial Automation: CTs find application in various industrial processes to monitor current levels and ensure optimal performance of electrical machinery.

  • Renewable Energy Systems: In renewable energy installations, such as solar and wind farms, CTs are utilized to measure the current generated and ensure efficient power distribution.

  • Building Management Systems: CTs play a role in building management systems to monitor electricity usage, support load management, and improve overall energy efficiency.
