Parallel operation of generators conditions

WebDec 9, 2016 · Generator Ratings. When evaluating generator sets for parallel operation, ratings are important because the rating directly affects the efficiency and effectiveness of the selected generator set based on the application. It is especially important to understand the specific application, as this will help in selecting the proper rating. WebTo properly parallel a generator using the three-bulb method, the generator should be brought up to a few RPM over synchronous speed and the excitation should be adjusted so that the voltages on the two sides of the switch are approximately equal. If the phase sequences are correct, then the bulbs should be glowing and be darkening together.
