Induced Voltages by Power Lines 1

[Terence483]

Hi,

I'm looking for a formula that would calculate the induced voltage on a pipeline trace wire that is running parallel to a high voltage power line.

Thanks

 

[Terence483]

Or where I could find it would be great also.

Thanks

Terence483:

You can use the method of IEEE 575, to calculate the required induced voltage as following.

Ep=jw(Ib)*2*(10 power (-7))*{0.5*ln(Sap*Scp/Sbp)+jSQRT(3)/2*ln(Scp/Sap)}

Where:
Ib:Current in conductor b
w:angular frequency = 2pf
Sap:axial spacing of the parallel conductor and phase (a) conductor
Sbp:axial spacing of the parallel conductor and phase (b) conductor
Scp:axial spacing of the parallel conductor and phase (c) conductor
Its assumed that the phase rotation is such that:
Ia = a Ib
Ic = a2 Ib
Where
Ib = Io (1+j0)
Where
Io=magnitude of the load current.

If it is useful for you, pls. mark it by * as helpful.
Bye
