Calculate professional protection relay settings for transformers, motors, MCC, PCC and other electrical equipment. 112, IEC 60255, and other international standards. Detailed mathematical breakdown compliant with IEEE C37. Effective relay protection depends on. The conven-tional approach to calculating relay protection setpoints loses its effectiveness, as a result of which the sensi-tivity and selectivity of protection decreases, and situations arise when it is impossible to select universal setpoints for all modes of operation. The relay settings that are selected are often a compromise in order to cope with both overload and. This technical report refers to the electrical protections of all 132kV switchgear. Protection selectivity is partly.
