CIRCUIT BREAKERS

nnnn

Currents produced from 2,000 MW power plants require protective solutions ensuring fast and effective

nnnn

power plant protection that guarantees the connection from the generator terminals to the grid.

nnnn

With 40 years of field experience and 200 references in nuclear power plants in 20

nnnn

countries, Alstom Grid offers you a complete and integrated solution: the PKG

nnnn

Generator Circuit Breaker.

nnnn

The PKG offers flexible operation and efficient protection for all types of power

nnnn

plants up to 2,000 MW, ensuring switching security for the connection between

nnnn

the plant and the transformers.

nnnn

Proven technology - extreme performance

nnnn

To interrupt an electric arc, the PKG air blast generator circuit breakers use the proven

nnnn

technology of compressed air, provided by an external compression station. In order to

nnnn

withstand the very high rated current, added fans, radiators and a cooling turbine placed on

nnnn

the top of the pole cool the contacts.

nnnn

Rigorous tests in the factory, test laboratories and in large public utility power stations show

nnnn

that 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

nnnn

PKG Generator Circuit Breakers are tested and manufactured in accordance with the

nnnn

International Standard IEEE C37.013.

nnnn

• Continuous production for

nnnn

maximum revenue

nnnn

• Safe maintenance thanks to

nnnn

integrated line disconnect switch

nnnn

• Unrivalled experience in the nuclear

nnnn

applications field
