In an electrical conductor, if current flows because of flow of electrons, then why not the conductor gets thinner day by day???
1 364610Hp, 3-phase, 415v, 50Hz induction motor. The above motor is to run on Star-Delta connection, so how do i make following hardware selection 1) MCB, 2) Contactor, 3) Wire Gage (Depending on P-P current or Line Current), 4) OLR, Please tell in detail how to do the above, so as to get the ans. of it even if the Hp rating changes.
1 6282Can we use a window type neutral CT instead of a bar type neutral CT. We have an issue with a neutral bar type CT of 800/1 ratio with a Circuit breaker NS800L shneider type, and we want to change it with a window type. Pls advise. Thanks
1 3352Lt trivector meter with ring type CT.Spec of meter are 3x240 v, -/5A. Ring ct spec. are 60/5A, line voltage- IL .66/3.0KV..what is the multiplying factor
1 3642Why we Do not connect the windings of the motor in delta? & what would happen if we do that? I mean the winding themselves not the three lines that are coming to the motor?
1 3354If we connect a motor and generator together (I mean that the generator gives the motor electricity and the motor gives the generator movement) regardless the losses. Will the generator still generate and the motor still move?
