Example of Calculating 115kV Relay Protection Settings

Example of Calculating 115kV Relay Protection Settings

With this Protection Relay Setting Calculator, you'll be able to work out pickup current, time multiplier settings (TMS), operating time, coordination time interval (CTI), and plug setting multiplier (PSM) based on fault current, CT ratio, and the IEC 60255 curve parameters. LAY S TTIN LAY SETTIN of CT groups fThis 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. Plug Setting Multiplier (PSM) indicates how many times the determined relay secondary current (...
