20kV Two-Core Current Transformer (“U-Shaped Top” Design)

EWF-20DI

2-core epoxy-cast current transformer for a ≦24kV power system. For use with measuring or monitoring instruments, and protective relays. “U-shaped top” design for safety and for a shorter distance between two current transformers installed side-by-side, thus reducing the required width of the switchgear panel.

About the Product

This two-core current transformer is designed for a 20~24 kV power system and to be used in conjunction with measuring or monitoring instruments, along with protective relays. Insulated with Araldite® epoxy, this indoor-use current transformer is designed with a “U-shaped top”, which creates distance between the primary terminals and other equipment. This design increases electrical safety and shortens the necessary distance between two current transformers that are installed side-by-side, thus reducing the required width of the switchgear panel.

Product Features

  • For indoor application
  • Cast in Araldite® epoxy resin
  • Standards: IEC or IEEE
  • System Voltage: ≦ 24kV
  • Frequency: 50/60 Hz
  • AC/BIL: 50/125 kV
  • Benefits: Increased electrical safety; reducing the width of the switchgear panel
  • Additional specification or customization may be requested to comply with various electrical standards or special requirements.

    When a power system is in operation, it is imperative that the secondary of the current transformer(s) should not have an open circuit. When an open circuit occurs, an extremely high transient voltage will be induced, which can in turn damage the current transformers and the instruments at the secondary, or even posing a threat to personal safety. This CT secondary overvoltage protector offers protection from such accidental damage caused by secondary transient voltage.
