I have a huge generator 2.5MW and I need to calculate the mechanical energy (kinetic energy) it contains when it is running at rated speed (2975 R/min).
How can I do that and I quantities do I need ?
My goal is to relate how much electric energy the generator produces as depending on its...
I am already trying to implement your second suggestion in a different way. We can not reduce the speed of the motor during normal operation because then the interval between the test series would be much greater due to the time needed to ramp up the generator speed plus more energy would be...
The load is the device we are testing... and the duration of a test is usually 200ms. A series of such tests are conducted during a time interval for example 2 hours in which the motor-generator is most running idly.
The UPS idea means we should be storing the energy in batteries ? That means...
We have a slip-ring asynchronous (induction) Motor than runs a generator needed for electrical tests. We are trying to improve the energy efficiency of the set-up.
The generator spends most of the time running idly and the motor has to keep running during this process to maintain the speed...

Background:
We conduct electrical tests in our lab on electrical components (circuit breakers, switchgears,etc). In the lab we have a short-circuit Generator that generates the electricity for the tests. The generator is powered by an asynchronous motor...
Hi
We are measuring 3 Phase Power of an asynchronous Motor-Generator and have equipment installed on Phase 1 (L1) and Phase 3 (L3) to measure the current/voltage/power. I have some questions regarding the results.
Q) Why is the Power of Phase 1 positive and Phase 3 Negative ?
Q) How can...
