Outdoor-Type Current Transformers / Extended Range Current Transformers (ERCTs) for Revenue Metering (12~36 kV)
AWF-12, AWF-24, AWF-36
These outdoor current transformers for revenue metering, intended for 12~36 kV power systems, are used as part of an MOF (Metering Outfit) or for current monitoring. Insulated with UV-resistant cycloaliphatic epoxy resin, these medium-voltage (MV) current transformers are ideal for outdoor use and can be available as Extended Range Current Transformers (ERCTs) when requested.
About the Product
Intended for 12, 24, or 36 kV power systems, these outdoor-use current transformers for revenue metering 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.
This product range has 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.
AWF 12, AWF-24, and AWF-36 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.
Mainly used as part of an MOF (Metering Outfit), these current transformers can also be used for current monitoring purposes.
Specifications
- Standard: IEC or IEEE**
- Outdoor usage; Epoxy-cast type (Cycloaliphatic Resin)
- Frequency: 50 or 60 Hz
- System Voltage: 12~36 kV
