Calculation of Relay Protection Settings for Generators and Transformers
Differential Protection Relay Setting Calculator helps engineers calculate pickup current, slope, restraint settings, and relay parameters according to IEC 60255-187 and IEEE C37. 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 technical report refers to the electrical protections of all 132kV switchgear. All calculations are based on the available documentation/ information. These settings may be revaluated during the commissioning, according to actual and/or measured values. Protection selectivity is partly. In most cases the 110% NL limit is more restrictive than the FL limit and would be plotted on the coordination curve set unless the GSU impedance is < 7% or so (Zt at max GSU MVA rating). Like Differential, IDMT, overcurrent, REF, Earth fault E/F, Over flux, Over/Under voltage protection relay setting.
