Question: 1 / 1030

What is a method used for restoring generator field residual magnetism?

Replace the generator

Use a capacitor

Flash the fields

Flash the field is a commonly used method to restore generator field residual magnetism. By using a low voltage or battery to re-energize the field, residual magnetic strength can be restored. This is the most efficient and cost-effective method compared to replacing the entire generator or using a capacitor or adjusting the voltage regulator, which may not effectively restore the residual magnetism. Therefore, options A, B, and D are incorrect.
