One of the most promising activities of EKRA Engineering Research Center Ltd. is the project design of digital substations. This is one of the company’s core activities.

EKRA Engineering Research Center has experience in developing documentation using digital substation technology both for reconstruction and new construction.

The introduction of the innovative DSS technology is the next stage in developing the power industry, which consists of organizational and technical measures aimed at optimizing and improving the efficiency of power resource distribution and control production processes by using a new power facility management technology created in compliance with international standard requirements.

The implementation of the Russian Digital Substation project has both technical and economic benefits. Besides, the DSS technology contributes to the development of domestic production and science, and improves the energy security of Russia.
