What is the function of neutral CT in transformer? Turn ratio of typical CT for 2MVA transformer ? or relation between full load current of transformer and neutral CT ?
1 2808Good day everyone,currently in our premise we using 30kw slip ring motor with resistance bank which we use as forward and reverse at conveyor bar handling. So,my question is how do we calculate the resistance bank which is suit the motor. Kindly,assist me... thank you

2 4389I just purchased a 4 position cam switch to be used to operate a 3-speed blower motor. The motor is a 10 amp motor and has 3 wires that are used to control speed. The cam switch was rated at 660V 20 amps but when I received it, I noticed that it has AC-15 operational current rating (Ie) of 4/5 amps. If I am reading the label correctly. the 4/5 amps is related to 440v/220V (Ue). Other ratings are AC-3: 5.5A, AC2: 7.5A and AC-4: 1.5A. My questions are 1) Is it safe to use this switch with the motor I have 2) what is the difference between the 20 amp Ith ratting and the Ie operational ratings?

1 3052star connection for a 3 phase induction motor gives reduced starting current.but 1.732 times the rated current during run up period if the motor was designed to run on delta. Why can't we design the motors to run on star connection instead. It will remove the starting arrangement required making the construction an operation much simpler.
