Compact, outdoor, oil-filled, distribution class, wound type current transformer
SCOF outdoor rated distribution class oil-filled current transformers are compact wound type designs. These current transformers are build-to-order to customer specifications. SCOF current transformers can meet many applications for metering and protection with up to two (2) independent cores from 15 kV up to 38 kV. This current transformer is available with porcelain insulators, ANSI 70 gray porcelain as standard. Hermetic sealing of the design is accomplished using a gas cushion above the oil in the tank to prevent free-breathing outside moisture-laden air.
The SCOF has a reputation for reliable performance in service with a low field failure rate that is lower than the industry average.
- Revenue metering
- Relay protection
Why Hitachi Energy?
For revenue metering and protection in medium voltage networks, this conservative oil-paper insulated current transformer is extremely reliable for this lower voltage application where users have experienced problems with dry type units. Given the flexible construction, the design is very adaptable for meeting the most demanding applications. Hitachi Energy offers our users unique advantages as follows:
- Excellent application engineering support to ensure the optimum solution for the success of your projects
- Designed for diverse environmental conditions - from polar to desert
- Ability to match solutions to critical applications such as wide range metering, capacitor bank monitoring and others
- Dielectrically stringent production includes hermetically sealed design with 100% partial discharge testing
