ABB Models Earthing Switches to Improve Generator Circuit Breakers
Francesco Agostini, Alberto Zanetti, Jean-Claude Mauroux, ABB, Switzerland
ABB, a multinational leader in electrification products and power grid technology, develops generator circuit breakers (GCBs) that safeguard power plants around the world. GCBs must dissipate short-circuit current surges within milliseconds to prevent damage to the grid and power plant. A critical design feature is the earthing switch, which grounds energized parts of the system. Engineers at ABB use multiphysics simulation to model the currents and electromagnetic forces that arise in earthing switches and ensure that they can withstand the rigorous current capacity standards of the International Electrotechnical Commission (IEC).
