Residual Current Devices in Electric Vehicles Charging Installations

Published by Stanislaw CZAPP, Gdańsk University of Technology, ORCID: 0000-0002-1341-8276 Abstract. The main requirements of national regulations and international standards regarding protection against electric shock in electric vehicle charging installations are presented. The principles of using residual current devices (RCDs) in such installations are discussed. It is pointed out that RCDs are mandatory equipment forContinue reading “Residual Current Devices in Electric Vehicles Charging Installations”

Residual Current Devices in Installations with PV Energy Sources

Published by Stanislaw CZAPP, Gdańsk University of Technology. ORCID: 0000-0002-1341-8276 Abstract. The paper presents the principles of residual current devices (RCDs) application in photovoltaic (PV) installations. Provisions of standards in this regard are commented on, in particular, attention is drawn to the lack of obligation to use of RCDs in PV installations. The issue ofContinue reading “Residual Current Devices in Installations with PV Energy Sources”

The Effect of PWM Frequency on the Effectiveness of Protection Against Electric Shock using Residual Current Devices

Published by Stanisław CZAPP , Gdańsk University of Technology, Faculty of Electrical and Control Engineering Abstract. In the paper spectral analysis of the distorted earth fault currents in circuits with variable speed drives is performed. Effectiveness of protection against electric shock using residual current devices in circuits with variable speed drives for various PWM frequenciesContinue reading “The Effect of PWM Frequency on the Effectiveness of Protection Against Electric Shock using Residual Current Devices”
