Ramping up the load Explanation: Large machines don't like sudden changes in load, which is applied gradually to avoid stressing both mechanical and electrical components. -------------------------------------------------- Note added at 4 hrs (2018-07-18 12:30:08 GMT) -------------------------------------------------- If it were an electric motor, I would say "soft start". Sudden application of power to such a motor accelerates the rotor, whose inertia "resists" the propulsive magnetic field, resulting in a massive current surge. By analogy, a large load suddenly applied to a large generator will generate a huge torque and consequent stress on the shaft, bearings and generator mounts. There is, in fact, a device known as a homopolar generator that does exactly this: it is spun up and then effectively short-circuited, generating tens of thousands of amps for a variety of interesting experiments. -------------------------------------------------- Note added at 23 hrs (2018-07-19 07:47:47 GMT) -------------------------------------------------- Yes, you are all quite correct. I concur. Rate of change of load, steepness of slope (ie. load vs. time), etc. |
