This paper focuses on the integration of Digital Addressable Lighting Interface (DALI) devices in wireless sensor networks. Since different manufacturers usually deal with one aspect building automation - e.g. heating ventilation and air conditioning, lighting control, kinds alarms, etc. final system has subsystems which are finally taken to an integrated management system. The cost this process is consequently increased due additional hardware investment. Our main purpose provide end...

High-pressure sodium lamps are currently the main used in public lighting. However, possibility of using high-power light emitting diode (LEDs) for street lighting is growing continuously due to their greater energy efficiency, robustness, long life and control. The aim this paper study power quality networks based on LED high-pressure lamps. Both electromagnetic dimmable electronic ballasts, which can dim lamp output smoothly uniformly, have been connected equipment tested with different...

Augmented reality (AR) improves how we acquire, understand, and display information without distracting us from the real world. These technologies can be used in different applications industries as they incorporate domain-specific visualizations on a real-world screen. Mobile augmented (MAR) essentially consists of superimposing virtual elements over objects screen, to give added value enrich interaction with reality. In numerous plants, it is being for maintenance repair tasks, well...

The results of this summarized paper some discussed more detail its companion paper. This discusses emission from wind solar as well advantages disadvantages active passive filters.

This paper presents an analysis of current emission from low-voltage appliances in the frequency range 2 to 150 kHz. The electric vehicle is measured for different connection other devices (LED lamp, microwave oven, TV) showing presence primary and secondary emission. shows that a neighboring device can have strong influence on

Measurements have shown that the harmonic currents emitted by lamps with electronic ballast depend on circuit topology and existing supply voltage distortion. This paper quantifies impact of distortion supraharmonic current emission individual Light Emitting Diode (LED) compact fluorescent (CFL). It also characterizes several Power Quality (PQ) parameters when those are connected to pure sinusoidal waveform.

Power electronics has emerged a ubiquitous technology, which plays critical role almost any areas....

As the number of facilities adopting a Building Management System under Industry 4.0 paradigm increases, it is critical to ensure good health their operations. Business continuity and uninterrupted operations are key requirements for any building, which Power Quality Supply Reliability sophisticated monitoring can play an extremely important role. Submetering, as opposed bulk-metering, implies measuring power consumption individual units or appliances in building complex. An Internet Things...

The international standardization community is currently reviewing the supraharmonics distortion limits. These are harmonics which fall in frequency range 2 to 150 kHz. Power electronics has consolidated as a ubiquitous technology, also plays critical role this subject. Broadly speaking, these HF components due normal operation of electronic converters and switching techniques employed. paper presents measurements waveform from several illustrative facilities loads. Recent studies indicate...

Due to the myriad of loads that are collected into commercial grid-interactive efficient buildings (GEBs) focused on industry 4.0 paradigm, it is important ensure their proper electrical operation. The power quality (PQ) here requires a granular monitoring approach, reaching point where each device connected microgrid can diagnose whether its supply optimal. Otherwise, participate cooperatively in decision-making avoid anomalies or faults microgrid. In this work, we present cloud-based...

This paper presents the results of a set measurements to study changes in harmonic emission from domestic customer due introduction energy-efficient lamps (CFL and LED lamps). has been studied through both magnitude complex current. We can see that depends on are connected as background. Sometimes adding new device reduces sometimes it increases it. The current produced by aggregate loads is significantly smaller than algebraic sum each one separately. Therefore, be some cancellation effect...

This paper presents the measurement and characterization of voltage supraharmonic emission (in frequency range 2-150 kHz) at different European North American low-voltage networks. knowledge is needed to be able better predict impact new equipment on current distortion in network. work a discussion serving as guide for future standardization levels, it an overview real values measured power grid countries.

In electric power systems, any deviation with respect to the theoretical sinusoidal waveform is considered be a disturbance in quality of electrical grid.
