“…As shown in Figure 1e, a capacitor C storage can be added to store energy for later use by the electronic circuit. However, a diode rectifier is required to charge the capacitor, which reduces the power given by ( 4) [1]. To increase the output power and shorten the discharge time, the EFEH system requires a switching circuit, as shown in Figure 1b,c [1].…”

“…Therefore, there is a need for self-powered, wireless sensor nodes that are more environmentally friendly and minimize the costs associated with periodic maintenance. Energy harvesting (EH) offers a potential solution to this problem, as this technology enables the conversion of ambient energy into electrical energy [1]. This harvested energy can be stored in electrochemical batteries or capacitors for later consumption or used directly [2].…”

“…It has been shown that electronic systems requiring average power levels between 200 µW and 10 mW can be powered by energy harvesting systems from ambient sources [3]. There are many ways to harvest energy from ambient sources, such as thermal energy harvesting [4,5], solar [6], vibration [7], radio frequency [2], piezoelectric [8], magnetic field [9], or electric field [1], among others.…”

“…In AC systems, there is a capacitive displacement current between the energized conductor and the ground through the surrounding air that can charge a nearby capacitor, so that the energy stored in that capacitor, E C , can be expressed as half the product of its capacitance and the square of its voltage. An electric field harvester is designed to capture some of this energy [1]. The electric field generated by a transmission line is independent of the amount of current, as it depends only on the voltage applied.…”

“…A similar approach was applied in [14], using a 220 V power line as a reference, showing an average extracted power of about 47 µW. In [1], using a copper sheet wrapped around a 230 V power line, the authors harvested 367.5 µW. In [20], a similar EFEH method was applied using a power line insulator, and the authors state that up to 17 mW of continuous power can be extracted from a 12.7 kV medium-voltage power line.…”

Energy harvesting systems are key elements for the widespread deployment of wireless sensor nodes. Although many energy harvesting systems exist, electric field energy harvesting is a promising choice because it can provide uninterrupted power regardless of external conditions and depends only on the presence of AC voltage in the grid, regardless of the magnitude of the line current, even under no-load conditions. However, it also has some disadvantages, such as low power availability, the need for storage, or reliance on capacitive coupling, which is a complex phenomenon that depends on parasitic capacitances. This paper aims to provide useful and practical information on the possibilities of electric field energy harvesting for both high- and low-voltage applications. Since the objective of this paper is to quantify the physical limit of the harvested energy, it considers only the physical harvester itself and not the electronic circuitry required to transfer the harvested energy to the load. Theoretical, simulation, and experimental results show the feasibility of this energy source for low-power applications such as wireless sensor nodes.

Energy Harvesting Methods for Transmission Lines: A Comprehensive Review

Humanity faces important challenges concerning the optimal use, security, and availability of energy systems, particularly electrical power systems and transmission lines. In this context, data-driven predictive maintenance plans make it possible to increase the safety, stability, reliability, and availability of electrical power systems. In contrast, strategies such as dynamic line rating (DLR) make it possible to optimize the use of power lines. However, these approaches require developing monitoring plans based on acquiring electrical data in real-time using different types of wireless sensors placed in strategic locations. Due to the specific conditions of the transmission lines, e.g., high electric and magnetic fields, this a challenging problem, aggravated by the harsh outdoor environments where power lines are built. Such sensors must also incorporate an energy harvesting (EH) unit that supplies the necessary electronics. Therefore, the EH unit plays a key role, so when designing such electronic systems, care must be taken to select the most suitable EH technology, which is currently evolving rapidly. This work reviews and analyzes the state-of-the-art technology for EH focused on transmission lines, as it is an area with enormous potential for expansion. In addition to recent advances, it also discusses the research needs and challenges that need to be addressed. Despite the importance of this topic, there is still much to investigate, as this area is still in its infancy. Although EH systems for transmission lines are reviewed, many other applications could potentially benefit from introducing wireless sensors with EH capabilities, such as power transformers, distribution switches, or low- and medium-voltage power lines, among others.
