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.
