Use this Protection Relay Setting Calculator to calculate pickup current, time multiplier settings (TMS), operating time, coordination time interval (CTI), and plug setting multiplier (PSM) using fault current, CT ratio, and IEC 60255 curve parameters. Information required for relay calculations NERC compliance (PRC- 019,024,025,026,027 overview) Sample application, Global settings Phase Fault Protection 87 – Phase Differential Current 50 – Instantaneous Phase Overcurrent 50DT – Definite Time Overcurrent Ground Fault Protection (High- Impedance. This document outlines relay setting calculations for a 100 MW / 150 MWp solar power plant at Bhadla, Rajasthan, detailing protective relay recommendations, design inputs, assumptions, and methodology for ensuring the system's reliability and safety. The protective philosophy is fundamentally grounded on the understanding that faults or abnormal operating. In this thesis, it was studied which different standards, rules, equations, and demands apply when determining the settings for the protection.
