13 SEP 2023 UCOM-MHE-EDE-13-09-2023.- within the framework of the Cochabamba ephemeris, and with a Investment greater than one billion Bolivians, President Luis Arce Catacora marked a milestone Historical for the development of the Bolivian electricity sector, when inaugurating the transmission line Carrasco – Santivañez;the first in 500 kV (kilowol) of the country, which puts Bolivia at the level of the Electric sector of the neighboring countries of the continent.

This work will strengthen electric transmission in the central and eastern section of the system National Interconnected (SIN), allowing to transport the power of generation plants Hydroelectric, solar and wind that have different random availability levels. Likewise, it will supply national demand and the export market through a system of robust transmission, with a transport capacity of a network operated in larger tensions at 230 kV.

It should be noted that the design, engineering and construction of the line were totally made by Bolivian professionals of Ende Transmission and the contractor companies in charge of the work, demonstrating a high level of training and experience for the execution of foundations, assembly, laying of the cables and the optical cable of earth (OPGW).

The Carrasco – Santivañez transmission line is located in the municipalities of Entre Ríos and Santivañez, from the Carrasco and Capinota provinces respectively;It has a length of 235.65 km and A simple list configuration with four conductors per phase, separated at 1.1 meters.His commercial operation will benefit the entire Bolivian population, strengthening the electric transmission in the Santivañez – Carrasco corridor, whose availability often Be affected because of heavy rains and/or overflows of the river in the area.

This new infrastructure has two defined sections, the first with an altitude less than 1,000 M.S.N.M.(meters above sea level) begins in the Carrasco substation, and the second with a altitude between 1,000 to 4,100 m.s.n.m.Connect the line with the Santivañez II substation.

It should be noted that the design, engineering and construction of the line is properly 100% BolivianThe substations were built in “hand key”.This demonstrates the high Level of Bolivian professionals, as well as the contractor companies that carried out the Foundations, assembly and lying of the cables and the OPGW.

Santivañez houses the industrial park of the same name, which is also the largest in Cochabamba; So the implementation of this transmission line will grant the necessary solidity to the industries located in the place and those new ventures that anticipate settle in this region, contributing to consolidate the industrialization government headed by the President Luis Arce Catacora.

Ende Transmission, a subsidiary of Ende Corporation, made improvements to the control and protection system internal of a three -phase transformer in the Catavi substation of the Department of Potosí.With this task is guaranteed a reliable and safe operation of the transformer, a vital part for the Energy supply to surrounding populations.

If the importance of a power transformer is taken into account, the maintenance of this equipment It is very necessary to reduce the risks of incidents, breakdowns and false shots, in addition to prolong your useful life, a fact that allows the proper functioning of the electricity grid.

According to maintenance activities, it was evidenced that some protections electromechanics denoted an advanced natural deterioration by the years of operation, in that sense The efforts were carried out for replacement in compliance with the technical and corresponding security, together with the verifications and surveys that are required in these cases.

To do this, the specialized technical personnel made the replacement of the protections electromechanics, improvements and renewal of the control-protection circuits, the system of Ducteado of the transformer, complete electrical tests and the verification of hermeticity of the 25 MVA three -phase power transformer.

The company Enda Transmission, a subsidiary of Ende Corporation, in order to guarantee reliability and maximum availability of the equipment associated with the 500 kV Carrasco transmission line – Santiváñez, made the removal of dielectric oil samples, reactors of Main bar line and reactors, which were subsequently analyzed in the laboratory of oils that the company has in the city of Cochabamba.

For the extraction of oil samples, safety protocols and standards are followed international to guarantee the integrity of the process.Subsequently, the oil is analyzed in the Ende oil laboratory in Cochabamba.

Due to the voltage level, the power and its importance in the interconnection trunk system (STI), the Power transformers have online monitors of gas operation parameters generated, moisture content, partial discharges in bushings, oil temperature and windings, by What, the results obtained in the oil laboratory are a way to verify metrologically the measured values and therefore the increase in the reliability of the equipment.

ENDE Transmisión currently has a modern dielectric oil analysis laboratory in Cochabamba, to be able to carry out periodic monitoring of the oil condition of the transformers, with the purpose of making reconditioning and/or change of it in a timely manner, before the oil continues its deterioration and can produce failures in the transformers.

ENDE Transmisión, Ende Corporation, maintenance in a reserve reactor did (coil high voltage) in the Santivañez 230 KV substation, part of the interconnection trunk system (STI). The availability of these reserve reactors is of the utmost importance to an eventuality of unavailability of the other 6 reactors in service.

The maintenance of the reserve reactor consisted of changing a radiator following a leakage of Oil detected during monthly inspection works.The escape was located in the union of the main ducts to the cooling radiator, which prevented its repair, reason by which was decided to replace the entire radiator.

The radiator replacement works were completed successfully and without any incident, in addition The hermeticity review of the unit was carried out, being fully operational for use according to request.

To carry out this maintenance activity in the substation, a equipment of oil filtering called ETEA 500, with which the oil level was lowered inside the tank that It contains the reactor, in such a way that it allowed the extraction of the radiator without the oil spill. All work stages such as being disassembly and assembly of the radiator, were carried out with personnel specialized technical and professional transmission.

ENDE Transmisión, Ende Corporation, with the purpose of facilitating the control and supervision of the electricity grid that operates, has implemented a monitoring system in its SCADA system with a visualization tool called Electrical Board, which allows visualizing important data that the company needs to analyze and/or follow up continuous in “real time” of electrical behavior in the stages of generation and transmission of the chain of electricity.

When the SCADA system administrator is aware that centralizes, practically 100% of the electrical data of high voltage from Bolivia, different “boards” were developed, including for generation and transmission with indicators considered important to visualize.In this first stage a board has developed to show The behavior of the total generation versus the total demand of the system in megawatts, and another that shows a map of Bolivia with the demand of each department.Highlighting that the data shown in these figures are refresh, in the Board, automatically in a period of two minutes (programmable).

Today companies need information related to their management indicators, for some decades Gosses have been implemented boards, even in the financial area.These are boards that show a Summary of the behavior of some area of the company, usually through management indicators.End of transmission He currently uses this tool that has called it “electrical boards.”

UCOM-MHE-ENDE-01-06-2023.- The presidents of Bolivia, Luis Arce, and Argentina, Alberto Fernández, They opened this Thursday in the community of Yaguacua, of the Tarijeño municipality of Yacuiba, the line of International Interconnection Bolivia – Argentina “Juana Azurduy de Padilla de 132 kilovolts (kV)”, which It represents a historical milestone in the energy integration of both countries.

This work represents “the brotherhood between two countries that have a common history, each fighting for Improve the quality of life of Bolivians and Argentines.This interconnection line that joins Bolivia and Argentina is also important for the presence of an Argentine president – the second to visit Yacuiba after Juan Domingo Perón – who renews friendship and affection between two sibling peoples ”, The Bolivian head of state expressed.

Meanwhile, Fernández said that with Arce “we share the same look of our peoples, with equality and social justice, to promote and build a Latin America that is integrated (…).One of the How Lucho works for the progress of Bolivia and the peoples of Latin America is here, in the Construction of an electric plant that carries energy to the North Argentina, which needs it so much. ”
