Manufactured in 1923 by the German company AEG, Turbo-Alternator Unit No. III represents one of the most technologically advanced systems of its time within the Silahtarağa Power Plant. Comprising a 9,800 kW alternator and a 13,100 kVA generator, the system exemplifies early 20th-century high-performance engineering.
The axial-flow steam turbine operates at 3,000 revolutions per minute and utilizes high-temperature steam (420–450 °C) for energy conversion. Supporting systems include integrated lubrication and condensation units composed of oil pumps, heat exchangers, condensers, and water pumps.
The electrical infrastructure is equally sophisticated, incorporating a 10 kV busbar system, voltage regulators, current transformers, automatic circuit breakers, and monitoring devices to ensure reliable and uninterrupted power generation.
This unit, which has been preserved in situ with its original structural integrity, offers a rare opportunity to study historical energy conversion systems firsthand.
