Vetrino–Isaccea–Yuzhnoukrainsk Powerline
The Vetrino–Isaccea–Yuzhnoukrainsk powerline is the third 750 kilovolts powerline running from Ukraine to the European Union. History Construction of a 750 kV powerline from Ukraine through Romania to Bulgaria was agreed on together with construction of the South Ukraine Nuclear Power Plant. The agreement was signed in Moscow in 1982 by the electrical industry ministers of the Soviet Union, Romania and Bulgaria. The powerline started operating in 1986 and it was completed in 1988. Route The powerline starts in Bulgaria at Vetrino (Suvorovo) substation near Varna and runs northward. In Dobrudja it crosses the border between Romania and Bulgaria and terminates at Isaccea substation in Romania. From there the line crosses Danube River, which forms the border between Ukraine and Romania in a 938 metres long span on two 118 metres tall delta pylons situated east of Isaccea and runs than to Yuzhnoukrainsk substation situated just north of South Ukraine Nuclear Power Plan ...

Bulgaria
Bulgaria (; bg, България, Bǎlgariya), officially the Republic of Bulgaria,, ) is a country in Southeast Europe. It is situated on the eastern flank of the Balkans, and is bordered by Romania to the north, Serbia and North Macedonia to the west, Greece and Turkey to the south, and the Black Sea to the east. Bulgaria covers a territory of , and is the sixteenth-largest country in Europe. Sofia is the nation's capital and largest city; other major cities are Plovdiv, Varna and Burgas. One of the earliest societies in the lands of modern-day Bulgaria was the Neolithic Karanovo culture, which dates back to 6,500 BC. In the 6th to 3rd century BC the region was a battleground for ancient Thracians, Persians, Celts and Macedonians; stability came when the Roman Empire conquered the region in AD 45. After the Roman state splintered, tribal invasions in the region resumed. Around the 6th century, these territories were settled by the early Slavs. The Bulgars, led by Asp ...

Ruins In Moldova
Ruins () are the remains of a civilization's architecture. The term refers to formerly intact structures that have fallen into a state of partial or total disrepair over time due to a variety of factors, such as lack of maintenance, deliberate destruction by humans, or uncontrollable destruction by natural phenomena. The most common root causes that yield ruins in their wake are natural disasters, armed conflict, and population decline, with many structures becoming progressively derelict over time due to long-term weathering and scavenging. There are famous ruins all over the world, with notable sites originating from ancient China, the Indus Valley and other regions of ancient India, ancient Iran, History of Israel, ancient Israel and Judea, History of Mesopotamia, ancient Iraq, ancient Greece, ancient Egypt, Ancient Rome, Roman sites throughout the Mediterranean Basin, and Inca Empire, Incan and Maya civilization, Mayan sites in the Americas.

High-voltage Transmission Lines
High voltage electricity refers to electrical potential large enough to cause injury or damage. In certain industries, ''high voltage'' refers to voltage above a certain threshold. Equipment and conductors that carry high voltage warrant special safety requirements and procedures. High voltage is used in electrical power distribution, in cathode ray tubes, to generate X-rays and particle beams, to produce electrical arcs, for ignition, in photomultiplier tubes, and in high-power amplifier vacuum tubes, as well as other industrial, military and scientific applications. Definition The numerical definition of depends on context. Two factors considered in classifying a voltage as high voltage are the possibility of causing a spark in air, and the danger of electric shock by contact or proximity. The International Electrotechnical Commission and its national counterparts (IET, IEEE, VDE, etc.) define ''high voltage'' as above 1000 V for alternating current, and a ...

Electric Power Transmission Systems In Ukraine
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of posit ...

Energy Infrastructure Completed In 1988
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has mass whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rzeszów–Khmelnytskyi Powerline
The Rzeszów–Khmelnytskyi powerline is an electrical power transmission line between Ukraine and Poland. It is the only 750 kV-powerline in Poland and one of the few of it in the European Union of this type. History The decision to build this powerline was made in 1977 and it went in operation in 1985. The line went out of service after Poland joined the synchronous grid of Continental Europe (UCTE). However, there was a plan to re-activate this line after 2010 by constructing a back-to-back conversion station on the Polish end of the line, but this was not implemented. In 2016 Energoatom announced it was considering disconnecting unit 2 of the Khmelnytskyi Nuclear Power Plant from the Ukrainian power grid and using the powerline to connect to the Burshtyn TES energy island which operates on the European power grid, to facilitate exports to Poland and Hungary. In 2019 the Ministry of Energy created a consortium, Ukraine Power Bridge Company Limited, to progress th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Albertirsa–Zakhidnoukrainska–Vinnytsia powerline is a power transmission line between Ukraine and Hungary. It is a part of the former "Mir" transmission system between the Soviet Union and Comecon countries. As of today, it is the only 750 kV-powerline in Hungary and one of the few powerlines operated with this voltage in the European Union. History On 28 February 1974, the USSR, Bulgaria, Hungary, GDR, Poland and Czechoslovakia signed a cooperation agreement on construction of the 750 kV-line between Vinnytsia and Albertirsa, and substations Vinnytsia, Zakhidnoukrainska and Albertirsa. Construction started in 1975 and it went in service in 1979. Since the synchronization of the power grid of Hungary with that of the synchronous grid of Continental Europe (ENTSO-E) and because of economic reasons, the powerline went out of service in 1993, but was put in service again in 2002 after some new equipment was installed.
