Abstract:

Dalam sistem tenaga listrik, isolasi bermanfaat untuk memisahkan beberapa konduktor listrik yang bertegangan sehingga tidak menimbulkan loncatan listrik atau bunga api listrik antara konduktor-konduktor yang bertegangan. Minyak merupakan material isolasi berbentuk cair yang banyak digunakan untuk mendinginkan komponen listrik tegangan rendah, menengah dan tinggi. Isolator minyak sebagian besar berasal dari minyak fosil atau minyak mentah yang diproses secara khusus sehingga memiliki sifat-sifat sebagai isolator. Perkembangan dunia saat ini menuntut suatu produk yang bersih lingkungan dan nyama

Abstract:

In this study, an innovative approach to matrix-converter-based AC-–AC variable frequency drives (VFDs) is introduced. The possibility of using AC–AC matrix VFDs for reactive power compensation in conventional AC–DC–AC VFD-loaded power distribution lines is investigated. It is found that the interaction of a large number of conventional AC–DC–AC VFDs with a conventional capacitor-based local compensation device leads to overcompensation in 0.4 kV power distribution lines. This is due to the fact that the conventional compensation device is designed to compensate the lagging reactive power prod

Abstract:

All electrical energy is produced, transmitted and distributed at high voltages. In this case, the measurement of the amount of electricity is carried out by electricity meters together with voltage transformers (VTs). The largest capacities are transmitted and distributed on power transmission lines of voltage of class 750 kV. In Ukraine there are about two hundred measuring VTs of class 750 kV. In addition, power facilities have been actively built recently, which will also require the installation of 750 kV transformers. Working VTs of substations for a class of 750 kV may have great weight

Abstract:

The dielectric strength of insulating liquids of transformer acts an important parameter in the operation of transformer. Thus, great interest and many studies have been extensively done to improve the dielectric strength. One of study is the introduction of nanoparticle in the transformer oils. Study of the nanoparticles for the last few years had been found that, it can be dispersed in the transformers oils to be nanofluids and directly enhance the transformer performance. In this study, an investigation has been carried out to focus on the effect of silicon carbide (SiC) nanoparticle to AC

Abstract:

The issues of environmental impact of high-voltage transmission lines are becoming relevant in connection with the development of electrical networks of high voltage 110, 220, 330 kV, extra-high voltage (EHV) 500-750 kV and ultra-high voltage 1150 kV. The harmful effect of electric and magnetic fields on living organisms and, first of all, on humans, manifests itself only at very high voltages in the wires of the overhead line (OH) phases, and is dangerous when working under voltage. The direct influence of the electromagnetic field of lines on a person is associated with an effect on the card

Abstract:

Abstract Electrified railways include a system of cable and overhead lines. An analysis of the operation of alternating current (AC) electrified railways sections shows that the value of the induced voltage caused by the operation of the traction network can significantly exceed the permissible level on adjacent disconnected high-voltage overhead lines. As a consequence, this leads to serious injuries to operating personnel, including deaths, failure of electrical equipment. From this point of view, 1x25 kV 50 Hz AC railway system networks are considered the most dangerous. The electromagnetic

Abstract:

Railway lines in Poland are either equipped with 3 kV DC traction system or not electrified for traction purpose. Presently maximum line speed is 200 km/h while maximum train speed is 250 km/h. Speeding up limit for 3 kV DC traction is estimated to be around 220-230 km/h. Already present in Poland trains for 250 km/h are equipped with three electric power supply systems: 3 kV DC used in Poland, 15 kV 16,7 Hz AC used in Germany, and 25 kV 50 Hz AC foreseen to be used in Poland on high speed lines. Introducing 25 kV 50 Hz AC traction power supply will be associated with safety challenges, which
