Answer Posted / engr. kashif
Increase in V will cause the insulation of the winding to become weaker with the passage of time and eventually may become short, thus damaging motor and possibly surrounding components.
Increase in frequency causes an increase in motor speed and that may well be harmful as the motor is not designed to run at the new increased speed. This will also cause increase in the motors winding inductance, decrease in the current being drawn, increase in power losses.

How do i perform grounding of star point of Genset (400V) for making connection with step up transformer of DELTA-DELTA (400V to 20KV) ? while Genset itself has its own neutral and grounding bus bar inside genset breaker box whereas we have another neutral and grounding busbar in synchronizing panel next to genset at maximum distance of 6meter, would someone pls advice if we can only perform neutral grounding in synchronizing panel or should we ground neutral on both places inside genset breaker box and synchronizing panel.
