Monitoring. Binoculars are helpful for technicians during substation inspections. 50Hertz operates 74 substations and switching stations.
Combined Grid Solution. Inside view of the converter hall in Bentwisch near Rostock. The converter is the heart of the interconnector "Combined Grid Solution" to Denmark, which integrades grid connections of offshore wind farms for the first time.
Safety First. Rescuers at sea and in the air practice special rescue situations. 50Hertz and various wind farm operators jointly maintain a rescue helicopter located on the island of Rügen.
Exchange. Conversation during a tour in one of the 50Hertz substations and switching stations.
Inspection. With an optical device, a technician checks necessary distances in a substation.
Maintenance. A 50Hertz technician is checking a switching gear valve at an offshore platform in the baltic sea.
