“…Currently solar battery and PTC-based power-tapping from ground wire are the usual way to power on-line monitoring devices of HV overhead transmission line [1,2]. For the former, the available power is too small and the device is bulky, while for the latter the way isn't applicable to devices at earth potential.…”

Overhead transmission line, on-line powering, ground wire current, power distribution. Abstract. Power-tapping from ground wire is an ideal method to power on-line monitoring devices of HV overhead transmission line. And the way with bus-like power-tapping coil plays an important role for its simple engineering and excellent lightning protection performance. The key to the PTC way is whether enough power is available from ground wire. Study has revealed that for PTC of certain size and material the available power from ground wire is variable. Hence, to study the distribution performance of power from ground wire bears great reference value for the power-tapping design and installation of on-line monitoring device. In view of the power is in proportion to square of ground wire current, the power distribution performance is obtained through analyzing ground wire current of power-tapping circuit. Besides, effects of concerned factors on it are analyzed using EMTP-ATP program. Results show that the available power increases from the vicinity of terminal tower to middle zone of line, and tends to be stable when it is about 10 spans away. Besides, conductors transposition could reduce the current evidently while others show little impacts. Finally, on-cite measurements verified the above-said analysis.

“…References [12,13] studied a method of electric field energy harvesting based on the principle of capacitance. Other papers [14][15][16] explored the feasibility of obtaining power from the shield wires of a transmission line. They indicated that this form of power supply can be a feasible and cost-effective alternative for feeding small loads existing along a high-voltage transmission line compared to other forms of power supply.…”

An energy acquisition system for the ground wire of an overhead transmission line can provide a continuous and stable power supply for an on-line monitoring device. Its key issue is how to obtain enough power. To solve this problem, an energy acquisition scheme based on the double-insulated ground wire of an overhead transmission line has been investigated in this study. Three energy acquisition schemes were proposed, equivalent circuit analysis models of the three energy acquisition schemes were established, and the maximum power acquired was theoretically analyzed. The energy acquisition power of the three energy acquisition schemes for different tower-type sizes was also analyzed. A simulation model was built in PSCAD. The effects of load impedance, length of energy acquisition wire, grounding resistance, and load current on the power acquired were analyzed. The research results of this paper provide theoretical guidance for choosing an energy acquisition scheme and for designing key parameters in practice.
