Answer / gupta.bhuvan

self starting problem of single phase AC motors. Single
phase isn't able to create torque by different magnetic fields.
So capacitors etc. are used to overcome this problem.

Answer / shahidniazi

when we use only single winding then no rotating flux so in
single phase motor is not actually single phase but split
phase mean 2 windings so that will produce rotating field
and rotor will move.

If We are converting the SINGLE PHASE AC into THREE PHASE AC by using STATIC CONVERTERS , then How do we bring the frequency to 50 hz??

I have 11KV/415V power distribution transformer. I have found unbalance current in LT (415V) side. Also observed that unbalance voltage (3V) at LV side due to HV side unbalance voltage. What should I check for this? Also, the same LV side load can run in balance on captive power.
