nnnnCIRCUIT BREAKERS
nnnnCurrents produced from 2,000 MW power plants require protective solutions ensuring fast and effective
nnnnpower plant protection that guarantees the connection from the generator terminals to the grid.
nnnnWith 40 years of field experience and 200 references in nuclear power plants in 20
nnnncountries, Alstom Grid offers you a complete and integrated solution: the PKG
nnnnGenerator Circuit Breaker.
nnnnThe PKG offers flexible operation and efficient protection for all types of power
nnnnplants up to 2,000 MW, ensuring switching security for the connection between
nnnnthe plant and the transformers.
nnnnProven technology - extreme performance
nnnnTo interrupt an electric arc, the PKG air blast generator circuit breakers use the proven
nnnntechnology of compressed air, provided by an external compression station. In order to
nnnnwithstand the very high rated current, added fans, radiators and a cooling turbine placed on
nnnnthe top of the pole cool the contacts.
nnnnRigorous tests in the factory, test laboratories and in large public utility power stations show
nnnnthat the PKG is perfectly reliable and capable of extremely high performance such as:
nnnn> 275 kA breaking of short-circuit
nnnn> 50,000 A rated currents
nnnnPKG Generator Circuit Breakers are tested and manufactured in accordance with the
nnnnInternational Standard IEEE C37.013.
nnnn• Continuous production for
nnnnmaximum revenue
nnnn• Safe maintenance thanks to
nnnnintegrated line disconnect switch
nnnn• Unrivalled experience in the nuclear
nnnnapplications field
