Electrical and thermal consumption related to buildings, whether civil, commercial, public, or of any other kind, is very much in focus today. With today’s targets for energy savings, reduction consumption, environmental impact, it necessary carry out retrofits modernize installations their management. The realization an effective improvement requires a careful analysis the case study because e...

When using electrical equipment in installations operating hazardous areas endangered by potentially explosive atmospheres, care shall be taken also to the selection of such equipment. The correct for use atmospheres must considered design phase an installation and verified mounting phase. Equipment intended designed, manufactured placed on EU market considering provisions ATEX Directive 2014/3...

Interactive Mixed Reality installations combine multimedia with novel multimodal interaction techniques. As an example of mixed reality environments the “Sensoric Garden” seven installations shown during a festival in Bremen are described. As this kind of event cannot be evaluated in terms of usability or effectiveness, we need other categories to assess the attractiveness or “joy of use” of in...

OBJECTIVE To investigate whether residence before and after birth near 50 Hz high voltage installations increases a child's risk of cancer and whether risk correlates with the strength of the magnetic field. DESIGN A population based case-control study. SETTING Denmark. SUBJECTS 1707 children under the age of 15 with leukaemia, tumour of the central nervous system, or malignant lymphoma d...

Electric Utilities Company of Nigeria (EUCN) have traditionally used electromechanical (EMR) distance relays for the protection of transmission lines in the past, and many such relays are still in use in power systems today. In this paper, microprocessor-based protective relays (MPBRs) applications in the Nigeria power systems protection were investigated. This paper evaluates the performance o...

If electrical and non-electrical equipment used in underground mines susceptible to firedamp coal dust or other industries with explosion hazard is not proper selected for operating explosive atmospheres, they are likely generate an ignition of the atmosphere result events significant environmental material damages and, moreover, human victims. Therefore, it mandatory responsible persons reach ...

Purpose. Performing the analysis to determine energy-efficient modes and assess characteristics of main indicators electric power consumption by mine water-drainage installations based on developed research mathematical model. Methods. To achieve purpose set, a methodology is used develop multiple multifactor correlation-regression modeling with respect electrical mechanical complexes installat...

Following the Brent Spar controversy, the OSPAR countries reached a unanimous agreement in 1998 for the future rules for disposal of petroleum installations. The vast majority of existing offshore installations will be re-used or returned to shore for recycling or disposal. For installations where there is no generic solution, one should take a case-by-case approach. We provide a survey of inte...
