What is a transformer station? Function, structure and significance for the power supply
Transformer stations also as Substations or grid stations, are essential components of our electricity grid. They ensure that electrical energy is transported efficiently from the power plant to the end consumer. But how exactly do they work and why are they so important for our energy supply? Find out more in our transformer station wiki article!
Definition and function:
A transformer station is an installation that supplies electrical energy from a Medium-voltage grid (typically 10 kV to 36 kV) to the voltage required for Low-voltage grids required 400/230 V. This transformation ensures a reliable and efficient supply to households and businesses. Without grid substations, it would be impossible to use electricity in the form that is common today.
Construction of a transformer station (Trafo-Wiki):
- Transformer - the centrepiece of the transformer station, which converts the voltage.
- Medium-voltage switchgear - connects the station to the medium-voltage grid and enables the system to be switched and protected.
- Low-voltage distribution - distributes the converted low voltage to the end consumer.
Construction methods of transformer stations:
- Walk-in stations: Larger systems that offer sufficient space for maintenance work.
- Compact stationsSpace-saving units that are often used in urban areas.
- Container stationsMobile transformer stations in a container housing - ideal for flexible, temporary use in industry.
Significance for the power supply:
Transformers/stations are indispensable for supplying energy close to the end consumer. They ensure that electrical energy is transported safely and efficiently from the generator to the consumer. These stations therefore make a significant contribution to the stability and reliability of the electricity grid.
Safety aspects (transformer station wiki):
Transformer stations generate low-frequency magnetic fields, the strength of which depends on the load and the distance. Magnetic flux densities of around 100 microtesla can occur on the outer wall of compact stations, which corresponds to the limit value of the 26th Ordinance on the Implementation of the Federal Immission Control Act (26th BImSchV).
Conclusion - Trafo-Wiki:
Transformer stations play a central role in the modern power supply. They enable the necessary conversion and distribution of electrical energy and thus make a significant contribution to the stability and reliability of our electricity grid. A transformer station bridges the gap between medium voltage and low voltage safely and efficiently - an indispensable part of any modern energy infrastructure.
FAQ: Further questions
When do I need a transformer station?
A transformer station is required when electrical energy needs to be converted from medium to low voltage. This is particularly the case for larger energy projects such as industrial plants, charging stations and solar parks.
What does a transformer station do?
A transformer station converts medium voltage into low voltage and distributes the electricity safely to various end consumers. It thus ensures a stable power supply and protects the grid from overload.
How many kW does a transformer station have?
The output of a transformer station can vary greatly and is often between 100 kW and several megawatts. The exact output depends on the requirements of the respective project. All products
How much does a transformer station cost?
The cost of a transformer station depends on its size and area of application. Typically, the costs range from several tens of thousands to hundreds of thousands of euros. Send transformer enquiry
How often does a transformer station need to be maintained?
