Efficient Voltage Transformation and Distribution for Optimal Energy Supply

The High-Voltage Power Supply (HV Power Supply) is an essential power distribution component tailored to steel and aluminum plants. It delivers operational safety and reliable power distribution and is designed according to utility requirements and the specific power demands of steel and aluminum plants. This system enhances power distribution and incorporates comprehensive protection systems crucial for steel and aluminum plant processes. Furthermore, the High-Voltage Power Supply (HV Power Supply) from Primetals Technologies is suitable for connecting renewable energy sources to conventional grids. It also features a modular design for scalability, ensuring seamless integration with existing and future technological advancements.

The High-Voltage Power Supply (HV Power Supply) efficiently supplies power to steel and aluminum plants, ensuring each production section receives the necessary energy to operate. A key feature is its flexible design, which accommodates specific customer requirements, process needs, and utility demands. Transformers step down high-voltage to medium-voltage, making the power suitable for steel and aluminum industry applications and ensuring efficient energy distribution throughout the plant.

When designing the High-Voltage Power Supply (HV Power Supply), it is crucial to consider grid operation and customer-specific needs. In addition, power system studies are performed by experts from Primetals Technologies, including isolation coordination, short circuit analysis, load flow, and protection coordination, to ensure an appropriate design for each High-Voltage Power Supply (HV Power Supply). State-of-the-art air- and gas-insulated switchgear is controlled via a modern SCADA and protection system, ensuring quick resolution of electrical issues and minimizing downtime. The switchgear's modular design allows for easy expansion and adaptation to customer-specific demands.

Benefits of the High-Voltage Power Supply (HV Power Supply)

  • Power distribution concept: flexible design for specific customer requirements and grid operation modes according to utility requirements
  • Increased reliability and production safety: advanced control and protection systems, including vacuum circuit breakers and multifunctional protection relays, quickly resolve electrical faults, minimizing downtime and ensuring safe operations.

Features of the High-Voltage Power Supply (HV Power Supply)

  • Gas-insulated and air-insulated switchgear: these options include electronic multifunctional protection, measuring, and monitoring relays in each switchgear feeder. These systems provide essential control and protection functions such as overcurrent, under- and overvoltage, and ground fault protection, ensuring operational safety and reliability.
  • Flexible design: easy expansion and customization enable steel and aluminum plants to adapt to different equipment manufacturers and production-specific requirements.
  • Power systems study: depending on specific requirements, the power systems study will indicate the need for features like isolation coordination, short circuit analysis, load flow, and protection coordination.
  • Renewable energy: suitable for connecting solar and wind power plants to conventional grids, and it includes a protection concept
