Põlva 110 kV substationPõlva, Põlvamaa

Põlva substation is a standard 110 kV substation comprising two 110/35/10 kV power transformers and three 110 kV overhead transmission line columns. This renovation project was especially interesting but also complex due to the need to connect circuits to the old substation that is still partly functioning. In addition to the construction of the substation, two 110 kV overhead transmission line masts and one 60 m communications mast were erected. Relay protection works were done also at Võru and Kuuste substations that are connected to Põlva substation. Thanks to the new substation, the reliability of the transmission Network of South-East Estonia has improved.
