Outdoor Current Transformers with Cycloaliphatic Cast Resin Insulation 12 - 36 kV
The current transformers series SGF are maintenance-free cast-resin transformers for outdoor application. They comply with various national and international standards (IEC 60044-1/-6, VDE 0414, DIN 42600, ÖVE-P20, ANSI, GOST etc.).
The current transformers are designed for ambient temperatures from -40°C up to +50°C and for operation up to 1000m above sea level (>1000m on request).
- system voltage Um up to 36 kV
- rated current up to 2500 A
- short time current Itherm. Up to 50 kAeff / 1sec
- accuracy up to class 0.2S
- frequency 50Hz or 60Hz
- up to 3 cores for metering and/or protection
Our instrument transformers can be delivered in a calibratable design for metering purposes. Type approvals for calibration are available for several countries.
We also produce current and voltage transformers in special designs and specification - we are looking forward to your inquiry!
