Impact of Pollution Location on Time and Frequency Characteristics of Leakage Current of Porcelain Insulator String under Different Humidity and Contamination Severity [PDF]

Journal of Operation and Automation in Power Engineering, 2007
One of the important factors influencing outdoor insulators performance is pollution phenomenon. The pollution, especially during humidity condition, reduces superficial resistance of insulator and lead to a flow of Leakage Currents (LC) on the insulator

Phantom citations: An empirical study of non‐existent and unverifiable references in scholarly literature

Journal of the Association for Information Science and Technology, EarlyView.
Abstract The integrity of scholarly communication depends critically on the accuracy and verifiability of cited references. Citations enable readers to trace prior work, assess evidence, and situate new contributions within the existing literature. However, concerns have emerged regarding the presence of references in published papers that cannot be ...

A Business Framework for Product Take‐Back—A Structured Multiple‐Case Analysis

Business Strategy and the Environment, EarlyView.
ABSTRACT The potential of take‐back systems remains largely unrealized as initiatives have proven difficult to implement in practice. The question is why we do not see more take‐back systems given the substantial environmental benefits. We try to understand the challenges and stumbling blocks in setting up take‐back from a business perspective.

Risk Assessment of Polluted Glass Insulator Using Leakage Current Index Under Different Operating Conditions

IEEE Access, 2020
In this article, an innovative approach to assess the risk of uniform/non-uniform pollution and wet high voltage glass insulator is proposed. The assessment is based on a new index, named as Rh', which is derived from the 3rd, 5th and 7th harmonics of ...

African Twist of Circular Economy: Insights, Policies and Recommendations

Business Strategy and the Environment, EarlyView.
ABSTRACT While the circular economy (CE) has gained traction, this paper argues that mainstream CE approaches risk being misaligned in the African context. Drawing on a mixed‐methods synthesis of empirical studies, policy documents and cross‐country examples, the study shows that Africa's CE transition is fragmented and uneven, leaving the continent at
