AC Current Transformers

Introduce:

SCT range of ac current transformers have been specially designed to facilitate their installation in new or already existing net works.

They may be installed without opening any cable or bus-bar circuit. An ineternal precision resistor across the secondary winding of the ct provides a low safe voltage output.

Features:

  • The structure of the self-locking, safe, easy to install, portable.
  • Wide inner window, allowing clamping of big cables or bus-bars.
  • SCT range of ac current transformers have wide range of sizes to accommodate all the existing installations.

Applications:

  • Current measurement, monitoring and protection for electrical wiring and equipment.
  • Current and power measurement for electric motors,lighting,air compressor,heating and ventilation system,air-condition equipment and automation-control system.
  • SCT range of ac current transformers have relay protection device.
