Bulbs Onstage: Theatrical Hygiene and the Electrification of Performance

European theatres were electrified between 1883 and 1913. This process has traditionally been associated with the advent of modernist theatre, but the details have rarely been examined, nor has the scope of the process's social and technological impacts been analysed. Reconstructing light bulbs’ early appearances in theatrical practice and discourse, this article traces the intricate entanglement between the electrical industry and theatrical culture around the turn of the century and highlights electricity's entanglement with concepts of hygiene and healing. Discussing an early light bulb in use in Bayreuth in 1882, the marketing strategies of the German Edison Company and Adolphe Appia's early manifesto, the article shows how electrification of theatres was shaped by competing visions of a future theatre. Also it demonstrates that aesthetics, technology and politics were intricately entangled in this process. Refuting teleological narratives of aesthetic progress, the paper proposes reframing modernist theatre's artistic autonomy as dependent on its embeddedness within the technologies of modernity.

Using X-Road to Implement Open Data in Electrical Systems and Promote the Integration with Smart City and Open Governance Strategies

The electrical industry is undergoing a deep digital transformation towards the consolidation of smart grids, which requires a high demand of data and information systems involved in the processes. Open data initiatives, which have been focused on open governance to a great extent, generate positive impacts on society and the economy in terms of easy access to public resources, agility, and transparency. These initiatives can also be adopted in the electrical industry (i.e., power, electrical, and energy systems) for customer engagement, collaboration with other industries, and reaching consensus. This study proposes the implementation of an open data solution for the electrical industry through the deployment of a data hub that offers digital services for smart city applications and the integration of the X-Road system to improve the security and interoperability of open data. This initiative aims to promote a wider adoption of open data in the electrical industry and prepare the latter for fully connected and collaborative digital ecosystems in smart cities, industries, and governments. This study also proposes an open data architecture for the interoperability of the electrical industry with other digital industries (through a Smart City Hub and the adoption of 5G technology), and it reports some relevant results and major findings in this regard. This paper highlights the benefits of promoting open data and technological strategies for digitized electrical systems while considering humans an essential factor. Finally, it discusses the pros and cons of the integration of X-Road with the electrical industry under the concept of smart grids for data exchange and potential applications.

Patterns for Resilient Value Creation: Perspective of the German Electrical Industry during the COVID-19 Pandemic

The COVID-19 pandemic represents a massive, often unanticipated, external disruption for many companies. As a concept for responding to such disruption, organizational resilience has recently received great attention. In the organizational context, the overriding question is how companies can become more resilient. This study aims to contribute to answering this question by identifying, categorizing, and providing specific business model patterns for achieving resilience on the corporate level. For this purpose, a review of publications by major consulting firms was conducted. Patterns were extracted from publications until a convergence criterion indicated that no new pattern could be identified considering further publications. The 110 extracted unique patterns were clustered into 13 objectives, and additionally categorized according to resilience phases, as well as business model elements, to support the application in practice. The final catalog of patterns was validated through expert interviews and thus provides organizations, such as those in the electrical industry, with an overview and specific approaches on how to tackle industrial resilience through the adaption of their business model.

AUDIT AND DIAGNOSIS IN ASSET MANAGEMENT AND MAINTENANCE APPLIED IN THE ELECTRICAL INDUSTRY

In the framework of asset management, the effectiveness of an integrated process that manages reliability and maintenance should be adequately and timely evaluated based on a thorough analysis of a series of contributing factors, which should respond entirely to the result of maintenance activities on the performance of assets that make up the production process. According to the above, then arises the motivation for the design and application of tools to determine the effectiveness of such activities in asset management, understanding the latter as a holistic process that involves a diversity of functions and areas within an organization

The Identification of Problems in Production Process Using Elements of Second Toyota’s Management Principle – Case Study

The paper presents a case study of the practical use of BOST surveys to identify problems that are the most important in production process. The research object is company from electrical industry. It was made the identification and of areas geneating problems from the second Toyota’s management principle point of view. Analysis of the research results was presented in the form of tables, histograms, radar chart and some statistical tools. Some production workers of the company with the help of BOST questionnaire survey showed, which factors are the most important. The aim of the analysis is to present which factors are the most important by building the significance sequences of obtained results. The results obtained for the type of small and medium-sized enterprises overlap with the results of tests verified in other enterprises.

Identification of Stray Gassing of Dodecylbenzene in Bushings

Several high voltage condenser type OIP (oil impregnated paper) bushings used in the electrical industry are filled with dodecylbenzene, because of its ability to absorb hydrogen formed by corona partial discharges in the thick paper insulation of these pieces of equipment. Some of them form large quantities of ethane, raising the concern of overheating faults in their paper insulation, which may be risky for their safe operation in service. The article presents dissolved gas analysis results of oil samples taken from the bushings with high ethane formation, together with results of laboratory tests of stray gassing of dodecylbenzene performed according to CIGRE procedure. By using Duval Pentagon 2 it is possible to compare patterns in the laboratory and in bushings and evaluate the temperature range of possible defects. Stray gassing/overheating of dodecylbenzene in bushings within the stray gassing temperature range and whatever the possible other causes, is not a concern for their safe operation according to observations published by CIGRE.
