Should the length of the cable be considered twice?

Hello to all. Should the following formula be used to calculate the voltage drop of the motor in the delta condition in a star-delta system considering that there are 2 cables between the panel and the motor and the current of this cable is 1/1.73 of the motor current? voltage...

Hi everybody I would be thankful if anyone explain me about the scientific or standard reference about using of differential relay instead of distance relay in short lines.some specialists believe that SIR>>>5 (approximately 10) is the basis of selecting 87 instead of 21.I would be grateful that...
