Abstract
An electronic load regulation system for a locomotive may comprise a solid state replacement for existing electro-mechanical load regulators that are used to adjust the excitation current in the field windings of the locomotive's generator. A pressure sensor may include a first chamber and a second chamber, each chamber having a pressure switch. The pressure sensor may be installed in place of a prior art vane motor and may connect to the existing governor hydraulic output. The pressure switches send status data to an electronic load regulator circuit that may replace a prior art rheostat. The electronic load regulator may increase or decrease the excitation current depending upon the status data received from the pressure sensor.
