Generator And Regulator Schematic
(1) Voltage droop transformer. (2) Voltage droop rheostat. (3) Lead. (4) Main stator.Operation of generators in parallel requires voltage droop as reactive load is increased. Droop transformer (1) and adjustment rheostat (2) are required to provide the voltage droop function. The transformer senses load current in lead (3) of main stator (4). Droop rheostat (2) provides adjustment of droop voltage. Rheostat (2) is located directly next to the regulator on the regulator mounting bracket. Droop transformer (1) is a special ratio transformer. Droop transformer (1) must be installed with transformer polarity connections as shown in the preceding schematic illustration. On 10/12 lead generators droop transformer (1) must be installed on generator phase lead T8. On 4/6 lead generators droop transformer (1) must be installed on generator phase lead T2.
