“…O. Menéndez studied a mechatronized maximum power point tracking system to automatically vary the location of the electrodes for harvesting the maximum electric-field power. The results show that the harvested power rises by approximately 94%, with a power density of 0.04l W/cm 2 in non-contact applications [59]. J. Rodríguez proposed flyback conversion in pulsed energy transfer mode so that the system is self-triggered to harvest 23.6 mW from a 12.7 kV power line [60].…”

With the development of intelligent modern power systems, real-time sensing and monitoring of system operating conditions have become one of the enabling technologies. Due to their flexibility, robustness and broad serviceable scope, wireless sensor networks have become a promising candidate for achieving the condition monitoring in a power grid. In order to solve the problematic power supplies of the sensors, energy harvesting (EH) technology has attracted increasing research interest. The motivation of this paper is to investigate the profiles of harnessing the electric and magnetic fields and facilitate the further application of energy scavenging techniques in the context of power systems. In this paper, the fundamentals, current status, challenges, and future prospects of the two most applicable EH methods in the grid—magnetic field energy harvesting (MEH) and electric field energy harvesting (EEH) are reviewed. The characteristics of the magnetic field and electric field under typical scenarios in power systems is analyzed first. Then the MEH and EEH are classified and reviewed respectively according to the structural difference of energy harvesters, which have been further evaluated based on the comparison of advantages and disadvantages for the future development trend.

“…According to the power line coupling, electric-field energy harvesters are broadly classified as cylindrical or multi-plate topologies [8,[12][13][14][15][16][17]. In general, the incorporation of metallic electrodes on the transmission line electric field creates an electrical network that could be seen as a capacitive voltage divider, in which complexity depends on the electrodes' number and disposition [17]. If the harvester is in contact with the line, the network is reduced to two capacitors (C 1 and C 2 ) serially connected [11].…”

“…Despite the success of HV/MV harvesting approaches, the development of low voltage applications has several constraints due to source scarcity and design constraints [11]. To ensure high-accuracy data collection and continuous communication, low-voltage EFEH systems need the execution of low-power design methodologies based on the energy-efficient design of management circuits, optimized electrode topologies, and enhanced communications architectures [17]. Preliminary findings showed that a 60 cm long aluminum harvester could gather 4.7 mJ in 1 min [20], while a 20 cm long cooper harvester is able to collect 20 mJ in 15 min [16].…”

Because traditional electronics cannot directly use the alternating output voltage and current provided by electric field energy harvesters, harvesting systems require additional regulating and conditioning circuits. In this field, this work presents a conditioning circuit, called serial switch-only rectifier (SSOR) for low-voltage electric field energy harvesting (EFEH) applications. The proposed approach consists of a tubular topology harvester mounted on the outer jacket of a 230 V three-wires electrical cable (neutral, ground, and phase), in which terminals are connected to SSOR. We compare SSOR performance with classic electronic approaches, such as a full-bridge rectifier and voltage doubler. Experimental findings showed that the gathered energy by a 1 m cylindrical harvester increased in approximately 73.3% using the SSOR as a power management circuit. Experimental findings showed that the gathered energy by a 1 m cylindrical harvester increase in approximately 73.3% using the SSOR as a power management circuit. This increase is principally due to the fact that a serial bidirectional switch disconnects the harvester from the rest of the management circuit, enhancing the charge collection process. Although simulated results disclosed that SSOR increased collected energy for smaller-scale harvesters (experimental tests obtained using a 10 cm cylindrical harvester), additional losses in bidirectional switch reduced its performance. In addition, we introduce a comprehensive analysis of EFEH systems based on SSOR according to the mains frequency for future power systems.
