Current LimiterMV Fault Current Limiter

General Description

IEC 62271-1, IEC 60282-1, IEEE Std C37.302, NEMA
ISO 9001, KEMA, CESI, CE, TUV, UL, ASTA
Seismic design, ETGI-1.020, IEEE Std 693, NCh2369
Structural design, ASTM A325, ANSI/AISC 360, AWS D1.1
High altitude correction per IEC 62271 & IEEE C37, ~ 5000m
Reduction of harmonics, voltage sags and flicker due to the lower total source impedance
Providing a very high and fast fault-current breaking capability at high operating currents
Available for medium voltage ratings up to 40.5kV, 6,300A and 200kA rms breaking capability
Implementation of the project-specific setting values for the instantaneous current and rate of current rise
