# Estimation of Synchronous Generator Mechanical Damping

We know that the no load acceleration torque of a synchronous generator is given by the equation (Ta = Tm -Te - Td) where Td = Dw and D being the damping due to rotor losses. Is there a way of estimating or measuring the damping based on the machine nameplate and without running the machine?

• Hello zarbtc, just a note that you can use MathJax in your question to write proper formulae. Note it works a little differently here than on other 'stacks. – rdtsc Oct 25 at 17:34
