“…With the rapid development of electronic information technology, various electronic and electrical equipment are constantly being updated and replaced, and the problems of electromagnetic interference (EMI) are becoming increasingly serious, which has brought serious harm to fields such as petrochemicals, aerospace, and substation equipments [1][2][3][4]. Therefore, the measurement of electric fields has become particularly important [5].…”

Considering the limitations of battery-powered active EO modulated electric field sensors, a photovoltaic cell-powered electric field sensor is designed, fabricated and experimentally demonstrated. The sensor is consisting of a laser photovoltaic cell-powered supply circuit, a receiving modulation circuit, and an induction antenna. The laser photovoltaic cell power supply circuit which composed of a power supply laser, a photovoltaic cell, and a DC-DC conversion circuit is designed and fabricated. Experimental results show that the photovoltaic cell power supply circuit can output stable voltages of 5 V and 1.2 V for the receiving modulation circuit. A lightning impulse (LEMP) measurement system is set up and used to test the characteristics of the electric field sensor in the time domain. The experimental results show that the sensor detected pulsed electric field shows good consistency with the applied LEMP in the time domain and the dynamic range of the sensor is from 0.86 kV/m to 10.7 kV/m.

As electromobility and especially the electrification of public transportation develops, it is necessary to safeguard human health and minimize environmental impact. Electromagnetic fields generated by the current flowing through on-board batteries, installations, converters, propulsion, air conditioning, heating, lighting, or wireless communication systems in these vehicles may pose risks to drivers and passengers. This research investigates electromagnetic fields induced by extreme low-frequency currents and permanent magnets on electric and trolleybuses implanted in Lublin, Poland. The identification of electromagnetic fields concerned an electric bus model and two trolleybus models. A comparative analysis of the results obtained with the permissible limits in the environment was carried out.
