OREANDA-NEWS. August 11, 2010. ZTR conducted technical seminar “Creation of the effective service system for the transformer inventory of power supply companies of Ukraine”.

Commercial and technical managers of the following power supply companies: power association in Lugansk, Central power company, Poltavaoblenergo, Symyoblenergo and Chernigovoblenergo were the members of seminar.

Significant problems in the transformer inventory conditions of power supply companies where almost half of substation transformers related for voltage 35 -150kV were the necessity of carrying out such kind of seminar. No doubt that there are no “eternal” transformers and no alternatives to replacee the transformers reached the end of its service life. However, replacement in a short space of time is related to the required investment peak and as a result is not practicable.         

Therefore, main purpose of modern service system of “aged” inventories is realization of measures of condition restoration and service life prolongation of the equipment worked –out its service life that permits to reduce the required peak of investments, expand it according to time and replace the equipment in its systematic order.
