Project:  Reconstruction of main distribution and sub-distribution 0.4kV blocks B1 and B2

Year of execution: 2016./2017.

Investor and end user:  PE  EPS,  Branch  TENT Beograd, Unit:  TENT B

In 2016, implementation of the project aimed at reconstruction of main distribution and sub-distribution blocks 0.4kV in one of the largest thermal power stations in the country, TENT B was started.  The scope of the reconstruction included production, delivery and installation of withdrawable switchboards of main distribution blocks  and reconstruction and replacement of circuit breakers in the sub-distribution  blocks  B1 and B2.

In the course of the project implementation, the following actions were completed:

  • Preparation of project execution plan;
  • Demounting of existing LV distribution blocks and sub-distribution blocks at blocks B1 and B2;
  • Production, delivery and mounting of new distribution withdrawable switchboards of LV distribution of 0.4 kV at blocks B1 and B2, according to IEC 61439-1&2 standard;
  • Reconstruction and replacement of main supply switches in sub-distribution blocks;
  • Connecting the plant with existing consumers, as well as to the DCS system;
  • Testing the connections to DCS system and commissioning;
  • Preparing the as-built project plan.

The works were completed in May  2017.
