what is the difference between 'Control Transformer & Potential/Voltage Transformer'?

Answer Posted / ankush

A control t/f is one which gives constant o/p voltage and
current , so known as control t/f.
These are basicaly used in electronics circuits.
while PT are used for the measurement of voltages.
so simple......

A 500 V shunt motor runs at its normal speed of 250rpm when the armature current is 200A. The resistance of the armature is 0.12 Ω. Calculate the speed when a resistance is inserted in the field reducing the shunt field to 80% of normal value and the armature current is 100A.

In both 600/1000 V cable and 450/750 V cable, we can supply 415 V. However for distribution, all utilities are using only 600/100 V instead of 450/750 V. What is the reason?
