Here you can see a 3D model of a protection unit in a local distribution substation.
A protection unit (also known as a protection and control unit) is a specialized assembly within a local distribution substation.
It is used to monitor, control, and automatically protect the power supply, thereby ensuring the smooth and safe operation of the local power grid.
Sensors continuously monitor voltage, current, and temperature within the substation.
In the event of a fault (e.g., short circuits or ground faults caused by cable damage), the protection station isolates the affected network sections within milliseconds to prevent damage.
In modern “digital” local distribution substations, it also enables grid control centers to perform switching operations remotely.
In addition, it helps automatically balance fluctuating feed-in (e.g., from photovoltaic systems) and loads (e.g., heat pumps or electric vehicles).
Thus, the protection station is the “brain” of the local distribution substation, ensuring the transition from regional medium voltage (e.g., 20 kV) to standard household low voltage (400/230 V) for residential areas.
The photorealistic model is suitable for real-time applications and complex renderings.
The textures have a resolution of 4096 x 4096 px and follow the PBR workflow (Base Color, Roughness, Metalness, Normal).
