Relay Coordination Study: Selectivity Calculations | EEP
The scope of study involves calculating the settings for protective relays to achieve selectivity during faults ocurring in the electrical network for the 13.8 kV and 4.16 kV projects.
Transmission Line Setting Calculations – Beyond the Cookbook
There are several approaches for making relay setting calculations. One approach is to calculate a setting and then do a number of checks to verify that the calculated setting is acceptable.

Professional protection relay testing calculator implementing IEEE C37.90 and NETA ATS standards. Calculate pickup values, timing curves, coordination time intervals (CTI), and test injection
FEEDER PROTECTION CALCULATIONS & SETTINGS
Relay coordination is the process of selecting settings that will assure that the relays will operate in a reliable and selective way. In OC relays the coordination is based on the relay time-current
Relay Protection Settings (PSM, TSM, EL, OL, MF)
PSM (Plug Setting Multiplier) settings must be in accordance with IEC 60255-151 which specifies performance standards for overcurrent relays and the computation of operational
