can we run all LT motors at 360 volts which are normally
rated 415+/-10% voltage rating

Answer Posted / j.karthik

The above answer is correct. While we can run the motor
using the 360Volt then the motor will rotate only the lesser
amount of speed than the rated 3000/1500 rpm. and it cannot
give sufficient output...and also produces a heat in the
motor winding.......

Hi Suppose we have a wye/wye transformer which is grounded at both sides,in this situation, do we have ay ground transformer? in other words, ground transformer can do any thing more (while we have nuetral wire in both sides)? As the last question, what about 3rd harmonic? we have two choices: first using wye/delta transformer + ground transformer and second using wye/wye earthed connection.in the former choice, we dont have 3rd harmoonic at the secondary side but what about Yn/yn conection? do we suffer from 3rd harmonic in the Yn/yn connection?
