Answer / abhishek

OHB circuit-breakers are gas insulated circuit-breakers for outdoor installation. They are used in power distribution for controlling and protecting lines, substations, transformers, rectifier units, capacitor banks, etc. Thanks to the autopuffer breaking technique, they do not generate operating overvoltages. This means they are also highly suitable for retrofitting, where the plant insulating materials may be sensitive to dielectric stresses.
