Protective Relay Settings: motor_nameplate_voltage
Protective relay settings, coordination parameters, and motor/bus protection data per IEEE C37, IEEE 242, IEC 60255, and IEEE 3004 series. Covers: IEEE C37.112 inverse time-overcurrent curve constants (A, B, p, tr) and IEC 60255-151 constants (k, alpha); CT accuracy classes C100/C200/C400/C800 per IEEE C57.13; relay pickup guidance by ANSI device number; CTI per IEEE 242; motor nameplate voltages, surge withstand levels, vibration limits, and relay alarm/trip thresholds per IEEE 3004.8-2016; ANSI device function numbers for motor and bus protection (Tables B.1/B.2/B.3); online partial discharge assessment thresholds; and dual-tie bus differential CT scheme fault response results per IEEE 3004.11-2019.
