auxiliary loads การใช้

• Inside the locomotive, another transformer steps the voltage down for use by the traction motors and auxiliary loads.
• Some DC locomotives used motor-generator sets as " stepdown transformers " to produce more convenient voltages for auxiliary loads such as lighting, compressors but they are inefficient, noisy and unreliable.
• Two of the three generating sets, located ahead of the reactor compartment under the superstructure, can be used to provide approximately 4 MW of power for the propulsion motors while the third takes care of the auxiliary load.
