Summary: The liberalization of electricity markets has quickly changed the environment in which utilities operate. Customers are demanding improved reliability, transmission plant availability and system management. Rising demand for electricity and an increasing number of generation plants connected to the network have only added to the urgency. Utilities must be able to guarantee high quality power delivery and reduce the
number and duration of outages.
Against this backdrop, ABB has developed a new family of switching device: a circuit breaker combining one or more disconnectors and control gears. This combination works for both indoor and outdoor installations.
An IEC working group is preparing a new standard (the future
IEC 62271-205) to classify the switching device combinations as “assemblies” of high voltage devices. The aim is to have an International Standard (IS) ready by 2007. The Cigre working group, B3-02/03, is also working to provide basic guidance for the assembly of high voltage devices in an already existing substation design.
