About the Product

Intended for 12, 24, or 36 kV power systems, these outdoor-use current transformers for billing are insulated with Araldite® UV-resistant cycloaliphatic epoxy resin. Able to withstand solar ultraviolet radiation without deterioration in electrical performance, these current transformers are suited to long-term outdoor usage. The AWF Series products have been supplied to power companies in numerous countries of tropical maritime climate, where these current transformers have been exposed to high moisture and salt spray for more than 20 years while continuing to function with stable quality.

The AWF Series current transformers are available in various classes of accuracy (0.15S, 0.15, 0.2S, 0.2, and 0.3) and have a burden rating of B-0.5. In addition, they can be offered as Extended Range Current Transformers (ERCT)* if requested by the customer.

The AWF Series current transformers can be used for power monitoring or as part of a MOF (Metering Outfit) for a 12~36kV power system.

Specifications

  • Standard: IEC or IEEE**
  • Outdoor usage; Epoxy-cast type (Cycloaliphatic Resin)
  • Frequency: 50/60 Hz
  • System Voltage: 12~36 kV
  • Rated Primary Current: 50～600 A
  • ERCT* available by request

* The ERCT specifications enable the CT to maintain its rated accuracy and burden rating while measuring 1%~150% (or even 400%) of its rated current, surpassing the usual metering-class requirement (5%~100%).

** Other standards and specifications available.
