[vc_row][vc_column width=”2\/3″][vc_column_text]The Odessaoblenergo energy utility is responsible for supplying electric energy throughout the entire Odessa Region, Ukraine, with a daily transmission average of 660MW, reaching close to 1,000MW in peak moments. The energy is transmitted at 110kV and 50Hz.<\/p>\n

Odessa, the third largest city in the Ukraine, is the capital city of region covered by Odessaoblenergo, with over 1.1 million inhabitants. Located on the coast of the Black Sea, Odessa is one of the Ukraine\u2019s most important tourist attractions, in addition to being a cultural, scientific and industrial center and site of the country\u2019s largest sea harbor.<\/p>\n

Due to the region\u2019s economic and strategic importance, power supply continuity is a major concern at Odessaoblenergo, where in recent years efforts have focused increased transmission and distribution reliability.<\/p>\n

Similar to what is happening in other parts of the world; on-line equipment monitoring is seen as the main tool in increasing reliability, which is mainly dependent on transformer performance.[\/vc_column_text][\/vc_column][vc_column width=”1\/3″][vc_single_image image=”5707″ onclick=”img_link_large”][\/vc_column][\/vc_row][vc_row][vc_column]

<\/div>[vc_column_text]At the same time this need was observed, Treetech established in 2004, in the city of Zaporozhye, Ukraine, a commercial representation office covering all the countries in the CEI (former-Soviet Union). This made possible, in a joint work between Treetech and MEZ (Moscow Electrozavod) transformer manufacturer, a new three-phase, 110\/10.5-10.5kV 40MVA transformer purchased by Odessaoblenergo to be delivered already equipped with intelligent sensors, ready for integration into an on-line monitoring system.<\/p>\n

In a visit to Russia and Ukraine, from December 01st to 14th 2004, Eng\u00b0. Marcos Alves, from Treetech, visited in Odessa to deliver technical maintenance training and perform equipment commissioning for the Treetech equipment. Following the delivery of the transformer equipped with the Treetech intelligent sensor system, a demonstration was given of the ease in putting Treetech\u2019s Sigma monitoring system in operation by simply installing it on a computer and connecting it to the transformer by way of a pair of cables.<\/p>\n

On that occasion, the diagnosis\/prognosis functions of the Sigma Software were also demonstrated.[\/vc_column_text][\/vc_column][vc_column width=”1\/2″]
