Light sensing technology has been developed as a part of arc faults detection since 1980’s. Currently, optical fiber and point sensors are 2 types of light sensors which have been applied along with simultaneous over-current mechanism for arc flash relays. Due to the characteristics of light sensors, sensitivity and reliability of the relay may be affected by the ambient light. This paper proposes a new approach for arc flash fault detection by using spectrum of the light. Electromagnetic radiation means different element would emit spectra with unique wavelengths when their atoms are excited. Therefore, elements can be identified if specific emission spectrum are detected during the excitation period. In general, Copper and Aluminum are commonly used for conductors. By examining the spectrum of the light, arc flash can be accurately and quickly detected. In the experiment of this study, copper and aluminum are applied as conductors. The light spectrum for both materials are measured and recorded by an optic spectrometer during the arcing incidents. The results show that accuracy and reliability of the light-based arc flash fault detection operation can be improved by using the proposed method.","PeriodicalId":150498,"journal":{"name":"2018 IEEE IAS Electrical Safety Workshop (ESW)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129897764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drowning would occur when the skeletal muscles contract and the victim can no longer swim. It is theorized that the likelihood of receiving a deadly shock in a freshwater environment (such as a lake) is higher than the likelihood in a saltwater environment (such as a marina). It is possible that due to the high conductivity of salt water, the current shunts around the individual, while in freshwater, where the conductivity of the water is lower than that of the human; a majority of the current will travel through the individual. The purpose of this research is to either validate or disprove these claims. To address this, we used Finite Element analysis in order to simulate a human swimming in a large body of water in which electric current has leaked from a 120V source. The conductivity of the water was varied from .005 S/m (pure water) up to 4.8 S/m (salt water) and the current density through a cross sectional area of the human was measured. With this research, we hope to educate swimmers on the best action to take if caught in such a situation.","PeriodicalId":150498,"journal":{"name":"2018 IEEE IAS Electrical Safety Workshop (ESW)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115138792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the more prominent challenges is that pipeline facilities and sites are often unstaffed, in remote areas, and may be in extreme weather locations. Furthermore, pipelines are often located in shared right-of-ways with high voltage electrical utilities, and are cathodically protected which can cause unexpected electrical safety hazards on pipelines, equipment, and appurtenances. If a candid assessment was performed, a large percentage of pipeline maintenance and operations employees would likely be found to have only minimal electrical safety training and knowledge, yet routinely perform specific nonexposed energized electrical tasks such as lockout / tagout of equipment and starting an electric motor. This paper will introduce the concept of an Authorized Person as a means of recognizing this group of persons who routinely perform nonexposed energized electrical tasks as part of normal job duties to ensure they receive the appropriate levels training, knowledge, and tools as part of an electrical safety program. Often this group of persons can be an underappreciated aspect of an electrical safety program. Authorized Persons are a subset of Qualified Persons as defined by NFPA 70E, and are qualified for the task per NFPA 70E, but are only authorized to perform specific non-exposed energized electrical work. For the pipeline industry, this provides a convenient designation to distinguish between persons who have the training, knowledge, and skills to perform exposed energized electrical work from those that only perform non-exposed energized electrical work as part of normal job duties. New considerations for advancing electrical safety programs have been outlined in this paper due to the introduction of the Authorized Person concept.","PeriodicalId":150498,"journal":{"name":"2018 IEEE IAS Electrical Safety Workshop (ESW)","volume":"221 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132480537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The specific program taught at a local high school is the PLTW engineering pathway. In discussions with the program teacher during a project review meeting for a senior class, the offer of providing a basic introduction to electrical safety was presented. The current plan was to present some electrical safety basics to a classroom of students in the program during the month of May. Topics covered were standards writing organizations, engineering societies, Electrical Safety Foundation International (ESFi), electrical engineering with a focus on the power / industrial side (i.e. the hazards), and electrical safety around their homes. Planned homework assignments were provided. The intention of this program was to create interest in electrical engineering with a focus on electrical safety.","PeriodicalId":150498,"journal":{"name":"2018 IEEE IAS Electrical Safety Workshop (ESW)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124940775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This presentation considers recent efforts in NFPA 70E, Department of Energy, and Department of Defense to address electrical hazards beyond power frequencies (50/60 Hz) in electrical systems and equipment including battery banks, solar and wind power systems, DC transmission lines, lasers, accelerators, capacitor banks, electroplating systems, induction and dielectric heating systems, etc. Industries utilizing these non-power frequency electrical hazards include chemical, power generation and transmission, aluminum and steel, military, and research. Recent work in the classification of all shock hazards and all arc flash hazards will be used to take the thresholds for various types of injuries and present a method of performing risk assessments based on energy type, work task, exposure, equipment configuration and condition, environmental considerations, and worker knowledge, experience, training and condition. This approach to risk assessment for electrical work with all electrical hazards in all work environments will then be used for the controls to prevent injury, including Personal Protective Equipment (PPE), training, oversight, and co-worker responsibilities. This paper presents a method of risk assessment for electrical work considering potential exposure to all forms of electricity, in all electrical work environments, for all industries. This risk assessment approach will include traditional AC power, DC, impulse, and radiofrequency sources.","PeriodicalId":150498,"journal":{"name":"2018 IEEE IAS Electrical Safety Workshop (ESW)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129941118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
