19. The "charging current" of a transmission line means, the current need to "fill up" the line with current before any current can be delivered by the power line to an end use - just as a water pipe must be "filled up" with water before water can be delivered to a user for water use. Since electric power transmission lines have a capacitance, they have a charging current. Line-ground capacitance of a transmission line can be calculated from C=0.0388/log(Dm/Re)...
