This Excel template provides a structured relay schedule with columns: Relay Tag, Make & Model, Location, Protected Equipment, Rated Current, CT Ratio, Pickup (Is), TMS, Curve Type (SI/VI/EI/DT), Highset Setting, Definite Time Setting, Last Test Date, and Engineer. This Excel template provides a structured relay schedule with columns: Relay Tag, Make & Model, Location, Protected Equipment, Rated Current, CT Ratio, Pickup (Is), TMS, Curve Type (SI/VI/EI/DT), Highset Setting, Definite Time Setting, Last Test Date, and Engineer. Relay settings records are critical for protection coordination studies and maintenance audits. Plug Setting Multiplier (PSM) indicates how many times the determined relay secondary current (typically the CT secondary) exceeds the relay pickup (plug) current. It is the key quantity utilized in IDMT. LAY S TTIN LAY SETTIN of CT groups fThe scheme is selected for blocking of distance relay during a P. T failure condition without a fault of transmission line. Current Setting: The adjustment of the relay's pickup current by changing coil turns, expressed as a percentage of the CT's rated secondary current.
