On a peculiar feature of longitudinal differential protection of generators reacting to vector values of currents

The possibility of activation delay of longitudinal differential protection of generators reacting to vector values is considered. This work presents calculated data for currents of three-phase short circuits for a turbogenerator operating in combination with a transformer as a function of number of...

Description
Summary:The possibility of activation delay of longitudinal differential protection of generators reacting to vector values is considered. This work presents calculated data for currents of three-phase short circuits for a turbogenerator operating in combination with a transformer as a function of number of short circuited turns in generator winding.
