Your selection is very near to right selection subject to conditions that all motors do not need be started simulteneouly and maximum rating of individual motor is less than 100kVa.It is ensure that starting current does not exceed rated current of selected generator current rating. also ensure...
Yes!Engineer2K7! u can try testing a bad sample and adjust the over current device of the HIPOT Test Set to trip the test set by making it sensitive to trip and stop test if excessive leakage in found in your test case.Thus it will eleminate possibility of your apprehensions.

Hey friends!
1.Before providing the solution,we need to know about running of the generator is with grid or in isolation.
2.We should not mix up issues of U/F protection of turbine with load shedding relays since we keep margine between mimimum frequency levels tolerated by turbines and load...
I have never come across adifferential relay with triple slope settings. There are three settings which need be done.
1 Pick up current of differential element which is normally default set.
2. First slope seeting is kept equal to {% mismatch of HV and LV side CT's(if any) plus percentage tap...
