IEEE has dedicated standards in Arc-flash hazard mitigation and protection (IEEE 1584 & NFPA 70E) while IEC has integrated its arc-flash protection into the IEC 62271-200, High-voltage switchgear and controlgear …
Protection of the neutral conductor in three (3) phase systems needs to be given importance during design, particularly on reduced neutral conductor size and when the presence of harmonics is …
The impedance of a power transformer has a direct impact on the total cost of the power system. Cost of power transformer, protective devices, etc will be affected. Electrical Engineers …
IEC 60947-4-1 addresses coordination between the motor circuit protective devices and the motor starters. It also provides a method to measure performance of these devices if a short-circuit occurs. This …
Oil-immersed transformer cooling methods are consistent in both the IEC and IEEE. This designation is one of the few that is the same for both standards. Oil-immersed transformer cooling method …
Short-circuit calculation is one of the most important work to be undertaken in plant power distribution. A comprehensive, detailed and accurate short-circuit currents will be used in switchgear selection, protection …
