Lowrie-Hall electric current converter, manufactured by The Leeds and London Electrical Engineering Co Ltd, Leeds, 1892.
The Lowrie-Hall system was an early (1880s) system of distributing high voltage alternating currents generated at a central generating station. The electricity was distributed at high voltage using high-tension cables at. Converters like this were installed at customer's properties to reduce the voltage ready for local use.
