Answer / prakul

motor starting torque will reduced.
AND AS WE KNOW TORQUE IS DIRECTLY PROPORTIONAL TO SQUARE OF
THE VOLTAGE.

Answer / senthil kumar

When the motor gets low voltage the following points are
obtained.
1.Low starting torque
2.low speed
3.High current
4.High temperature rise
5.High power factor
6.Noise

Answer / binay agrawal

motor speed will gradually down, but at below half of the
full voltage, winding can burn.

Answer / l.madhavan

motor run with low speed

Answer / gunasekaran

it is rotating very slowly

Answer / dilip dixit

WHEN LOW VOLTAGE APPLY TO THE MOTOR THAN TORGUE WILL BE
HIGHER AND FOR THIS SLIP WILL BE INCREASE AND MOTOR WILL BE
TAKING HIGHER CURRENT & BURNT AFTER CERTAIN LEVEL.

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.
