Dear Professor, Scientists and Technicians in the field :
I'm looking up on how to determine the Charging Current in a distribution (15, 25 or 35 kV) overhead power line.
These lines are Polyethylene-covered cables. But, since there is always a non cero Capacitance between Ground and the line, there always exists a Charging Current in the direction from the phase, to the Ground.
Does anyone know about the subject ?
How I can compute such result ?
Charging Current.
Best Regards!
Hello. Take a look at this paper https://selinc.com/api/download/125783/.
I am not sure if its exactly what you're after but as for microstrip lines I would also follow the same logic using line models, I think it might be of use to you.
Hope it helps
Use the formula in this url

Good Luck!
When a line is opened, the voltage in open side of the line is increased , and causes a current to flow from the sending side of the line(the connected side of line to network).It is line charging current (the Ferranti's effect).A simple way for determining of it, is to measure the voltage difference between the sending and receiving sides of the line and to divide by the line impedance.
thank you
