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:
Technical drawings or data for the 110 kV high-voltage distribution systems that feed these specific railway grids. Regional Usage low-frequency-16.7z
Early electric locomotives used "brush-type" AC/DC motors that operated much more efficiently at lower frequencies. This specific frequency is a historical and technical
