Electrical switching plants with centralized protection. This solution enables considerable simplification, acceleration and cost-effectiveness of the building and exploitation of the plant and thus to increase the efficiency and reliability of the protection. Precodnition for application of such a solution is that all the voltages and currents from the measuring transformers are obtained in digital form, either by building up analogous-digital converters, or by applications of measuring transformers with integrated analogoous-digital converter. |
