  • Required changes in emission standards for high-frequency noise in power systems

    This paper discusses some recent developments that make the existing standards on the emission of high-frequency noise in power systems need to be reconsidered. It is shown that it is possible for an equipment to remain below the emission limits while at the same time the disturbance level increases beyond what was intended by the standard document. Further, the change from analog to digital ...

  • Case study - ABUTEC’s low emission technology eliminates light, heat, noise and environmental pollutions

    Over the last decade, Indonesia’s largest and most successful state-owned oil and gas enterprises faced significant problems with excess light, heat, noise and environmental pollutions. The facility, located in Mudi, Tuban, has grown to produce huge amounts of toxic and sour gas, making emissions a growing concern. The traditional, large pipe flares historically used to mediate the ...

  • Vehicle–road interaction for interior noise measurement and evaluation

    Nowadays, one of the most valuable criteria of vehicle quality assessment is based on acoustic emission levels. A vehicle is judged comfortable depending on the noise levels transmitted inside. Consequently, there is a general attention to the design criteria aimed at improving the structural acoustic behaviour, to comply with the increasingly restrictive ergonomic standard. Therefore, it is ...

  • Controlling the turbocharger whistling noise in diesel engines

    Turbochargers are now commonly used in passenger cars especially in application with diesel engines because of their numerous advantages. The use of this machine greatly improves engine performance, while at the same time allowing pollutant emissions to be reduced. However, one of the important issues to take into account when a turbocharger is used in passenger cars is the whistling noise due to ...

    The Company Aircraft engine manufacturer, NPO Saturn, was established on July 5, 2001 through the merger of Rybinsk Motors JSC and A. Lyulka-Saturn, a leading Russian aircraft engine design bureau. The company, founded by Pavel Aleksandrovich Soloviev, has its headquarters in the town of Rybinsk and holds a 50% stake in the PowerJet joint venture with Snecma. NPO Saturn is the leading Russian ...

  • A cure for Environmental Emissions case study

    Disposing of nearly 1 million pounds of medical waste a month is no easy task. The wet electrostatic precipitator, installed at Rochester, MN-based Mayo Clinic, seems to be just what the doctor ordered. While the medical waste incinerator at Mayo Clinic in Rochester, MN, consistently met state and federal emission requirements, facility leadership recognized that installing a wet electrostatic ...

  • Long-term noise monitoring – how a new approach leads to a better result

    Good Neighbours Limit their Noise Impact Long-term noise monitoring has taken place in various applications for many years. Business such as airports, power stations, refineries, mines, etc., may be required to perform continuous noise monitoring to ensure legal operating conditions are not breached, and to demonstrate to local authorities and communities that the business continues to be a good ...

  • A comparative performance evaluation of the conducted emissions in hard switched SPWM and HPWM inverters

    This paper presents simulation and experimental discussions on conducted electromagnetic interference (EMI) emissions for a single-phase full-bridge sinusoidal pulse width modulated (SPWM) and hybrid pulse width modulated (HPWM) inverters. The influences of input dc link voltage, modulation depth and carrier frequency on the conducted noise are studied through ICAP simulation software. HPWM ...
