Generator circuit-breakers protect important assets in power plants by clearing potential harmful short-circuit faults in tens of milliseconds, preventing severe damages and enhancing power plant availability.
Hitachi ABB Power Grids' generator circuit-breaker works behind the scene to protect power plants
For over 60 years, ABB’s generator circuit-breakers (GCBs) have been protecting all types of power plants around the globe. As the global leader in GCB technology, ABB is continuously driving innovation to provide solutions to increase power plant availability and reliability.
Strategic spare parts service solution for GCBs at Purulia Pump Storage Plant
Through the strategic spare parts solution , high-voltage service from Hitachi ABB Power Grids is ensuring uninterrupted power supply to more than 1.8 million Indian homes from Purulia Pumped Storage power plant in eastern India. Watch how the maintenance of GCBs was carried out in just 3 days instead of the standard 10, enabling cost savings of around USD 300,000 per shutdown.
Increase operational availability, safety and flexibility in all types of power plants around the globe
Hitachi ABB Power Grids is the leader in design and manufacturing of GCBs since 1954 with more than 8,000 deliveries in over 100 countries. We offer the widest and most modern portfolio of GCBs in SF6 technology across a range of short circuit ratings from 63 kA to 300 kA and nominal currents from 6,300 A to over 50,000 A to meet the demand of all types of power plants around the globe as well as synchronous compensator applications.
GCBs increase protection of key equipment like generators and power transformers, ensure power plant availability, simplify operational procedures and reduce costs. Our GCBs are manufactured in Switzerland. We offers unique features like lean manufacturing for the shortest delivery time and the ability to participate in Factory Acceptance Test (FAT) personally or remotely using Remote Factory Acceptance Test (RFAT) from any place with access to internet connection.
