| Аннотація | Parameters of the subminiature electromagnetic relays used as output elements in microprocessor relay protection, do not correspond to technical specifications on these relay protection. The reasons of this discrepancy are analyzed. Contradictions and discrepancies of the international standards in this area are considered. It is shown, that
absence of clearness in standards and mistakes in technical specifications of microprocessor protection manufacturers do not allow to estimate technical parameters correctly and lead to decrease in reliability of relay protection. |
