Data record qty.frequency.ieee1159.power-frequency-variation

Verified 2026-10-27 Confidence: High

IEEE 1159-2019 treats power frequency variation as the deviation of the fundamental frequency from its nominal value, a quantity that follows the balance between load and generation and that Table 2 lists as its final category.
