A 200 MVA transformer in the 330\/110\/22 kV system enables large loads to be transmitted directly from the main grid to consumers, reducing intermediate grid losses. The three-winding solution is particularly beneficial in situations where both the 110 kV regional network and the 22 kV local distribution require a simultaneous power source.<\/p>\n<p>During installation, a new concrete foundation was prepared, a full oil system with expansion tank was installed, and high-precision primary buses were constructed. Insulation tests, protection relay calibration, and final test loading were carried out in accordance with international standards, and the substation was commissioned on the planned schedule.<\/p>","protected":false},"excerpt":{"rendered":"<p>Supply and installation of a 200 MVA three-winding power transformer (330\/110\/22 kV) at P\u00fcssi substation, strengthening the Ida-Virumaa power system transmission capacity.
