cf4 Calibration for HV MV

IntroductionThe Circuit BreakerData Analysis1.1 THE ELECTRIC NETWORKElectricity is a natural phenomenon. It is a part of matter as negatively charged electrons and positively charged protons. Generating stations, usually located in remote areas far from the main centers of consumption, generates it by transforming other forms of energy (mechanical, thermal, solar, nuclear, e…1.2 POWER CIRCUIT INTERRUPTERSA power network needs to constantly change the circuits' configurations. That means to put in or out of service this or that part of the installation. Power circuit interrupters include a number of apparatus with the main task to connect and disconnect power circuits rated 1000 Volts and higher. Main circuit interru…1.3 MAINTENANCE STRATEGYApparatus on power circuits have to be robust and reliable, otherwise damage can be great on both hardware and personnel. Maintenance is crucial.
