In an electrical conductor, if current flows because of flow of electrons, then why not the conductor gets thinner day by day???
1 356310Hp, 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 6202Can 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 3286Lt 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 3561Why 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 3266If 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?

we have earthmat at 110KV substation.we would like to take earth resistance.b some says that by connecting earth megger terminals (C1,P1) at middile point of earthmat (at riser) will cause voltage gradient at other earthmat nods and dont get exat earth resistance.when connecting at end nods will get exat value . is it correct .please explain
