ORCID: 0000-0002-1628-1818 Abstract. Receivers such as power electronic devices, due to their widespread use and non-linear characteristics, are the most common cause of poor quality electricity. The share of non-linear receivers in the overall balance of power installed at a single customer increased to the level that the power supply voltage was affected by such phenomena as: overload of the neutral conductor, higher harmonics, and asymmetry. The article presents the assessment of electricity quality parameters based on measurements carried out at consumers. The assessment was based on the Regulation of… Impact of Climatic Factors on the Restoration Time of MV Power Lines Published by1. Kornelia A. BANASIK, 2. Andrzej Ł. CHOJNACKI, Kielce University of Technology, Chair of Power Engineering, Power Electronics and Electrical MachinesORCID: 1. 0000-0002-6629-8650, 2. 0000-0002-9227-7538 Abstract. The duration of outages (restoration time) is a fundamental parameter characterizing the extent of failures, as well as the quality of organisation during their elimination. Its understanding allows for estimating the costs incurred by consumers and electric energy distributors. Besides technical and organizational factors, the weather conditions during repair works also influence its value. This paper presents a statistical analysis of the impact of weather conditions, represented by air temperature, wind speed, and… Interference Present in the Electrical Installation with Special Consideration of Higher Harmonics Published by Marta BĄTKIEWICZ-PANTUŁA, Wrocław University of Science and Technology. ORCID: 0000-0002-1628-1818 Abstract. Converter devices, i.e. computer power supplies prevalent in buildings, as well as LED light sources, which have replaced traditional light bulbs due to their widespread use and characteristics, are the most common cause of poor power quality. The construction of the devices is based on semiconductor elements such as thyristors, diodes, etc. whose task is to adjust the network parameters so that the devices work properly, i.e. converting the alternating voltage into direct current and reducing its value in order to provide proper power supply. The share… Analysis of Power Quality Parameters at Facilities Connected to the Municipal Electricity Grid Published by 1. Aleksander CHUDY1, 2. Paweł MAZUREK1, 3. Korneliusz PAWLAK2, Lublin University of Technology (1), Ball Packaging Europe Lublin Sp. z o.o. (2) ORCID: 1. 0000-0002-3183-8450, 2. 0000-0002-7098-2084 Abstract. In the present study, power quality parameters across two residential blocks, a single-family house, and an industrial facility were studied and evaluated. Compliance was generally satisfactory, with occasional voltage harmonic exceedances in residential and industrial areas and exceedances in THDV and long-term flicker perceptibility in the industrial setting, highlighting the need for continued monitoring and potential mitigation strategies.

Ali Boukerche1, 2. Salima Lekhchine1, 3. Tahar Bahi2, Department of Mechanical Engineering, Faculty of technology, University of 20 August 1955, LGMM Laboratory, Skikda, Algeria (1), Department of Electrical Engineering,Faculty of technology, Badji Mokhtar University, Laboratory (LASA) , Annaba, Algeria (2) E-mail: a.boukerche@univ-skikda.dz Abstract. At present, energy saving and renewable energies represent one of the most important axes of sientific research. One of these renewable energies is solar energy, which has two aspects: solar thermic and solar photovoltaic; this energy is highly coveted due to its availability, but the cost of this energy remains very high, specially for… The Measurement of Power Consumed by an Industrial Robot under Dynamic States Published by Krzysztof OLESIAK, Czestochowa University of Technology ORCID: 0000-0003-4552-7810 Abstract. The paper presents a method of measuring power consumed by an industrial robot in a single phase system. A computer-based measurement set was constructed, consisting of special purpose voltage and current converters and a PC with a multi-channel measuring card. Measurements were conducted and time curves were recorded for the supply voltage and current of the robot under dynamic states at prescribed trajectories. The software DasyLab was used to plot time waveforms, to obtain power values and to record data. The power consumed by the robot was analyzed for… Developing an Expert System for Analyzing Defects on Production Lines Published by 1. Krzysztof KRÓL1,2, 2. Grzegorz KŁOSOWSKI1,2, 3.

Website: Dranetz.com SUMMARY Controlled environment agriculture (CEA) relies on advanced technologies such as climate control systems, artificial lighting, and hydroponic or aeroponic growing systems. These systems, in turn, require stable, clean power. This Application Note outlines how a New Jersey-based indoor farming facility addressed persistent HVAC and VFD failures by installing a Camille Bauer PQ5000 permanent power quality and energy meter along with Dranetz master monitoring station. The meter and station setup provided insight into utility feed conditions, helped diagnose internal power events, and offered actionable data to prevent crop loss. Indoor Cultivation Requires Reliable Power… Power Quality Lessons from an Controlled Environment Agriculture Facility Published by Dranetz Technologies, Inc. Website: Dranetz.com For controlled environment agriculture (CEA) operations, temperature, humidity, airflow, lighting, and CO₂ must stay within narrow limits 24/7 to foster growing conditions for high-value crops. When power quality deteriorates, environmental systems can go off-spec, putting these crops at risk. When HVAC and VFDs began failing unexpectedly, New Jersey CEA facility operators took a closer look at what was happening with power operations. This article highlights key lessons from a recent Application Note that documents how permanent power quality monitoring helped the facility move from uncertainty to confidence.
