Input Voltage Tolerances

Table 5.6 lists the input voltage tolerances for the single-phase 9900 subsystem. Transient
voltage conditions must not exceed +15-18% of nominal and must return to a steady-state
tolerance of between +6 and -8% of the normal related voltage in 0.5 seconds or less. Line-
to-line imbalance voltage must not exceed 2.5%. Nonoperating harmonic contents must not
exceed 5%.
