This specific frequency is a historical and technical standard used primarily for train traction. While most public power grids run at 50 Hz or 60 Hz, these railway systems operate at a lower frequency for several key reasons:
Lower frequencies reduce reactive power production in AC cables, allowing for active power transmission over longer distances with fewer losses. low-frequency-16.7z
