We have 2 types of VT in the power systems:
1- Inductive Voltage Transformer (VT or PT)
2- Capacitive Voltage Transformer (CVT)
The main difference between VT and CVT is that the CVT is
based on capacitive voltage divider principle which steps
down the high voltage to a lower voltage level that can be
measured easier. This can make the VT much less bulky (save
space) and also less expensive. This is why that for voltage
levels up to 132 kV, it’s common to use conventional VTs but
at voltage levels more than 132 kV we use CVTs.

I have a drawing of a wound rotor induction motor for a crane. This crane motor has 5 forward speeds & 5 reverse speed implemented of course with different amount of resistance for each speed setting selected. What has got me scratching around is the fact that 8 of the 10 speed selections switch in uneven (unbalanced) amounts of resistances on each of the 3 connections to the motor's rotor.Can this be possible? I would have assumed this would produce unbalanced rotor currents and therefore vibration in the motor. I would greatly appreciate anyone's comments on this. Many thanks, Confused.
