Poland 6 PS 400/110 kV

Control Systems & Secondary Circuit Installation

ELTEC50Hz Gridworx delivered the installation and integration of control and auxiliary systems within a 400/110 kV substation environment.

The scope included installation of eight 110 kV control cabinets, as well as dedicated cabinets for the 400/110/15 kV transformer field. Works also covered full implementation of secondary circuits across high-voltage (HV) and medium-voltage (MV) systems, alongside auxiliary power infrastructure, including 220V AC/DC and 48V DC cabinets.

The project ensures stable system control, reliable auxiliary supply, and a structured foundation for protection and automation systems.
