Current transformers – Type AGU
AGU current transformers feature an inverse design optimized for minimal oil content and reduced energy losses. Available with rated voltages from 72.5 kV to 800 kV, rated currents up to 6000 A, and short-time withstand currents of up to 100 kA (250 kA dynamic), they meet the highest industry standards. From its inception in 1947, KONČAR has established a trusted global presence, with over 60,000 units currently in operation worldwide.
Additional design features:
- Custom-made design – tailored to individual customer requirements
- Enhanced measuring range for current cores
- Partial discharge-free under AC test voltage
- Robust insulation system designed to withstand very fast transient overvoltages
- Oil expansion effectively managed by a stainless-steel membrane
- Broad operational temperature range from -60 to +60 °C
- Available in biodegradable insulating fluid-filled configurations
- Proven reliability in seismically active environments
- Resistant to internal electrical arcs (Internal Arc Classification II)
- High operational safety with minimal maintenance requirements
