  • Electrical Safety Considerations in Large-Scale Electric Vehicle Charging Stations
    IEEE Transactions on Industry Applications, 2019
    Co-Authors: O Wang, Payma Dehghania, Shiyua Wang, Massimo Mitolo
    Abstract:

    Several Safety regulations, particularly concerning the charging of electric vehicles (EVs) are developed to ensure electric Safety and prevent hazardous accidents, in which Safety requirements for the EV supply equipment (EVSE) and the EV battery are two main driving factors. At present, quantitative assessment of Electrical Safety considering the operation conditions of large-scale EV charging stations (EVCSs) has still remained a challenge. Driven by the hierarchy of hazard control mechanisms, this article proposes a holistic approach to evaluate the Electrical Safety of the large-scale EVCSs when coupled to renewable power generation. Our approach mainly focuses on several topics on the operational Safety of EVCS primarily concerning: 1) the facility degradation which could potentially result in a compromised EVSE reliability performance and EVCS protection failure; 2) the cyberattack challenges when the smart charging and the communication between EVCSs and electric utilities are enabled; and 3) the potential mismatch between the renewable output and EVCS demand, which could trigger the system stability challenges during normal operation and inability to supply the critical EV loads during outages. The proposed framework will provide informative guidelines to the EVCS operators for continuous monitoring and effective management of the day-to-day EVCS operation.

  • Electrical Safety of electric vehicles
    2017 IEEE IAS 53rd Industrial and Commercial Power Systems Technical Conference (I&CPS), 2017
    Co-Authors: Fabio Freschi, Massimo Mitolo, Riccardo Tommasini
    Abstract:

    This paper discusses fundamental Electrical Safety issues, and the protection against electric shock of persons interacting with electric vehicles. The Safety of users may be challenged by the vehicle's increased operating voltages, at different frequencies, possibly making more complex the protection against direct and indirect contacts. The electric Safety of the vehicle is herein examined in both normal operating conditions, and in the case of Electrical and/or mechanical failures; Safety during charging is also examined. Solutions to improve Safety are proposed, also in light of the evolution of the technology, and of applicable technical standards.

  • Arc Welding Processes: An Electrical Safety Analysis
    IEEE Transactions on Industry Applications, 2017
    Co-Authors: Fabio Freschi, Luca Giaccone, Massimo Mitolo
    Abstract:

    Manual metal arc welding can be a hazardous practice if proper precautions are not taken. The welding procedure uses an open electric arc between an electrode and the metals to be joined. Besides the obvious risks of burns and inflammation of the cornea, which are prevented by using proper personal protective equipment, the operator may also be subject to the risk of electric shock from the exposed parts of the welding circuit, both the electrode and the workpiece. In addition, the welding current, by straying from the intended path, can cause localized heating of parts, with the risks of triggering fires and/or explosive atmospheres. Because of the high current required by the arc welding equipment, operators are exposed also to strong electromagnetic fields. This paper seeks to clarify the aforementioned issues, especially in light of the fact that the risk associated with electric shocks may be unknown to welders and their supervisors.

  • Electrical Safety in the industrial workplace an iec point of view
    IAS Electrical Safety Workshop, 2014
    Co-Authors: Massimo Mitolo, Peman Montazemi
    Abstract:

    Electrical professionals working on the installation, construction, repair and maintenance of facilities are exposed to the risk of electric shock due to their possible interaction with live parts, but also due to the contact with the enclosure of equipment, normally not energized, which has become live under fault conditions. This necessary interaction with equipment for its intended use can, therefore, not be limited.

  • risk assessment myth busters defining risk management processes and terminology
    IEEE Industry Applications Magazine, 2020
    Co-Authors: Daniel Roberts, Rene Graves
    Abstract:

    I have seen the future of Electrical Safety and it is risk assessment. Or so it would seem, based on how the concept of risk assessment has become prevalent in standards, papers, and presentations over the last few years. Is the future of Electrical Safety risk assessment or risk management? This article explores the rise in acceptance of risk assessment in the Electrical Safety world. It also discusses the difference between risk assessment and risk management, hazards and risk, and the two basic risk assessment approaches.

  • Towards a globalization of Safety standards for Electrical work
    2015 IEEE IAS Joint Industrial and Commercial Power Systems Petroleum and Chemical Industry Conference (ICPSPCIC), 2015
    Co-Authors: Giuseppe Parise, Chaparala Satish, Luigi Parise
    Abstract:

    Asia, North America and Europe apply different standards to provide Safety for Electrical work. The progress of the Electrical Safety and sustainability for Electrical works appear more and more a necessity since Electrical installations are becoming complex systems especially for mission critical systems, microgrids and smart cities. The authors have analyzed basic standards such as European EN 50110, USA's NFPA70E, India's CEA Regulations and found that in spite of some diversities and different approaches, they lend themselves to a gradual coordination. Maintenance and Safety audits have a great role in Electrical Safety. Workmen's competence is essential for the reduction of risks in the Electrical operations. The efficacy of an operation and maintenance (O&M) that is compatible to business continuity management (BCM) principle is the basic component to control the Electrical hazards including the loss of power supply continuity risks. The paper highlights, as O&M has to adopt the continuous improvement principle of “Plan Do Check Act”.

  • Electrical Safety of street light systems
    IEEE Transactions on Power Delivery, 2011
    Co-Authors: Giuseppe Parise, Luigi Martirano, Massimo Mitolo
    Abstract:

    Street light systems are publicly accessible Electrical pieces of equipment out of the physical control of who operates/owns them. Street lighting systems typically include low-voltage loads, distributed in a large area, and are collectively protected by the same device. Under fault conditions, hazardous potentials may appear on the metal enclosures of these systems, and expose people to shock hazards. To reduce the risk to an acceptable level, different solutions for the bonding and grounding are available. The Standard IEC 60364 and a current worldwide tendency seem to encourage the use of Class II equipment for the street light systems. Class II components, such as the wiring systems, the light fixtures, etc., have double or reinforced insulation. In this paper, these authors analyze technical alternatives to protect against indirect contact in light of the IEC standards. In order to elevate the level of Safety offered by Class II metal poles, the adoption of special circuitry and bonding connections to continuously monitor the double insulation of metal poles is proposed.

  • Relevance of Competence in Risk Reduction for Electrical Safety
    IEEE Transactions on Industry Applications, 2008
    Co-Authors: Giuseppe Parise, Robert E. Nabours, Bruce L. Mcclung
    Abstract:

    The design of a power system is an assessment in Safety and functional performances correctible and perfectible during its life cycle with risk and quality management. Hazards exist and will continue to exist in a world of ever-increasing technology, so risk assessment is mandatory. Professionalism requires dedication by the individual; it needs the highest competence like major basis for decision making and for avoiding errors. In work activities, authority has to derive from qualification, responsibility has to imply competence. The competence of a person rests on a double root, related to conscious-unconscious that is objective characteristics and to sensorial-subsensorial that is subjective capacities.

  • District Heating Safety Issues: Interactions Between Grounding Systems and Thermal Installations
    'Institute of Electrical and Electronics Engineers (IEEE)', 2016
    Co-Authors: Cerino Abdin Giulio, Freschi Fabio, Mitolo Massimo, Poggio Alberto, Tartaglia Michele
    Abstract:

    The structure of a district heating network lends itself to interactions among the grounding system of the generating plant, and those of the users, with the possibility that hazardous- induced voltages may occur on the latter. Hazards are possible due to the bonding of the heating system pipes to customer’s ground- ing systems, as well as to possible high values of fault currents. These Electrical Safety issues due to grounding electrode inter- actions have been so far poorly treated in technical literature. District heating pipes are generally diElectrically separated in seg- ments by means of insulating joints. A deeper analysis of such joints shows that the hot water circulating in the pipes may bypass their insulation, rendering the effectiveness of the dielectric sepa- ration strongly dependent on the joint geometry, and on the water Electrical conductivity. The authors propose possible schemes for the hot water pipe connections, and discuss their efficiency based upon the Electrical configuration of the generation plant. An exper- imental verification procedure to assess the Electrical Safety of the district heating system is also proposed
