Motor Starting Methods: critical_voltage_limit
IEEE Std 3002.7-2018 motor starting study data: critical voltage limits during motor starting, autotransformer tap current and torque percentages, locked-rotor starting power factor by motor rating, reduced-voltage starter method comparison (voltage/current/torque), and net acceleration torque vs speed profile.
