Elimination rate of major defects in substation

More than 85%. According to the requirements of substation equipment defect management system, the annual elimination rate should be above 85% if the general defects have an impact on the operation, but they can persist in the operation for a long time. Substation refers to the place where voltage and current are converted, and electric energy is received and distributed in the power system. The substation in the power plant is a step-up substation, whose function is to boost the electric energy generated by the generator and feed it into the high-voltage power grid.
