Starting of large Induction Motor on Gas Turbine Generator
Originally posted by Arjun Sharma on 26 February, 2014 - 9:56 pm
Starting of the biggest Induction motor on Gas Turbine would trip the complex because of an instantaneous overloading is the concern. The voltage drop may also cause the tripping of downstreams. So, suggestions are required regarding the same.

Will RCC gain adjusted to zero cause a problem
Posted by Arjun Sharma on 28 February, 2014 - 10:44 am
The RCC was previously 6% and it was made 0% recently as recommended by the vendor for the site conditions. The above modification may arise a problem as there may not exist a voltage droop as far as my understanding goes.
