Auxiliary, trip & supervision KAR2S-CP—H-»- The effect of a fault on a power system is dependent on the speed with which the fault can be detected and isolated. Modern protection schemes incorporate ever increasing functionality through the application of digital techniques to protection relay technology. The requirement for highly reliable tripping and control relay elements does however remain and often constitutes a significant cost and space requirement when considering protection panel designs. The Actus system fulfills this need by providing a compact, flexible and high...
