FIELD: electrical and power engineering; high power flow transmission and distribution.
SUBSTANCE: proposed current transformer has grounded housing accommodating winding-and-core assembly incorporating magnetic core carrying secondary windings disposed around one of primary winding conductors and secured on grounded housing. Two high-voltage bushing conductors are coaxially disposed. Primary winding conductors are coaxially arranged within grounded housing and interconnected by means of conducting disk. Magnetic cores and secondary windings are disposed around internal primary winding conductor and secured to grounded housing. Vibration dampers made of insulating material are installed in high-voltage bushing between coaxial conductors.
EFFECT: enhanced reliability and dynamic resistance to short-circuit currents.
