Hybrid car on the drive system used in the study are two types of driving three phase induction motors and the Internal Combustion Engine (ICE) as a backup drive. On the second drive system is required movement drive transmission soft transition during the both movement of the drive. Therefore, techniques are required to control the electronic switch gear in the car drive transmission equipment...

In this paper the risk associated with deposition of aerosol (‘‘hygroscopic dust”) on printed circuit boards is assessed for different equipment designs and deployment. The amount of deposited dust is related to (1) the total dust availability in a given type of equipment and (2) to the rate of deposition of dust due to different mechanisms. Of these, the Brownian diffusion, gravitational settl...

Condition monitoring of power substations is a significant issue for the National Electric Power Authority (NEPA) of Nigeria. Current methods for monitoring the condition of high voltage equipment are time consuming and often inaccurate, therefore causing catastrophic damage to the substation equipment. Recent research has demonstrated the efficacy of employing optical fiber sensors in conditio...

The problem of electric field grading in cable components, having both theoretical and technological implications, can be framed in more general topic of field control in HV equipment. A solution may be obtained by two possible approaches: using geometric field control [11, 13, 14, 15, 17, 18], in which the field distribution depends on the arrangement of main and auxiliary electrodes or using ...

INTRODUCTION THE bulk of the Japanese market for monitoring and control systems for thermal and hydro power plants involves upgrades to existing equipment. The key requirements for this market are high reliability, the ability to undertake upgrade work quickly, an emphasis on compatibility with existing control equipment, and ease of maintenance. In markets outside Japan, meanwhile, demand for ...

ABSTRACT The application of on-line monitoring system for recording main welding parameters during electric arc stud welding process at different electric arc stability changes is described in this paper. In the first part of the paper, the basics of electric arc stud welding process, and equipment for stud welding and process monitoring used in experimental part is described. In the second par...

The transportation industry at present is moving towards electrification and the number of electric vehicles in market increased with different policies directorate. Consumers, who wish to contribute green mobility are concerned about limited availability charging points due high manufacturing costs interoperability issues related smart charging. This work proposes an Internet things-based low-...
