Well we were only testing this to measure the temperature differential between the coiled and uncoiled wire. We were told that the magnetic field induced by the coiled wire would increase the temperature of the conductor therefore increasing the resistance. Before testing, we wanted to get a...
Yes AC current is being passed through the cable, and skin effect + proximity effect should be taken into consideration since we are using a medium voltage (35kV rated) cable with an aluminum core.
Well the problem we ran into during testing was that the resistance increased when we measured coiled vs uncoiled. We are trying to determine whether or not this was a factor or the fact that the coiled wires are closer together (therefore increasing the heat of the wires) which in turn...
Hello everyone,
I was wondering how to calculate the added resistance experienced when a cable is coiled rather than layed flat due to the magnetoresistance of the magnetic field created by the solenoid configuration.
I will be running 250A though a cable which will be coiled like a...
