Relay Settings Calculations
To avoid relay mal-operation, set Slope 2 as high as possible. Normally, a high Slope 2 setting causes slow tripping for evolving faults (external-to-internal faults).
Protection Application Handbook
Fault calculation is the analysis of the electrical behavior in the power system under fault conditions. The currents and voltages at different parts of the network for different types of faults, differ-ent positions
Relay Coordination Calculator — IEEE C37.112 / IEC 60255-151 CTI
