Følsgaard Hosted Technical Event on Arc Suppression Coils

During the past week, Hans Følsgaard had the pleasure of hosting an exclusive professional event focused on arc suppression coils and their crucial role in modern power grids. The event was conducted in collaboration with Trench Group, a leading supplier of high-voltage components, who presented their latest technologies in arc suppression coil (Petersen coils) solutions.

Arc Suppression Coils and Their Importance in the Power Grid

Arc suppression coils play a critical role in electrical distribution networks, serving as an effective method for minimizing the consequences of ground faults.

These coils reduce ground fault currents by creating a compensating counter-reaction within the grid, thereby preventing thermal and mechanical damage to cables, transformers, and other critical equipment. This enhances supply reliability, extends the lifespan of electrical components, and simultaneously reduces maintenance costs and potential downtimes.

Trench Group’s Michael Babl provided in-depth insights into their advanced solutions, which can be tailored to both Danish and European infrastructure projects. One of the key topics discussed was how arc suppression coils fit into a power grid increasingly integrated with renewable energy sources, where capacitive ground fault currents from cables pose a growing challenge.

Expert Discussions and Technical Questions

The event brought together approximately 50 industry professionals, who contributed their in-depth technical expertise. Participants posed relevant questions and provided technical input, emphasizing the need for continued innovation and adaptation of technologies to local conditions. Some of the key discussion points included:

• Adapting arc suppression coils to changing grid conditions: The need for flexible and adaptive control systems that can adjust based on network conditions.
• Types of insulating oils: How different types of insulating oils affect the performance and lifespan of arc suppression coils.
• Corrosion in Danish environments: Specific challenges related to high humidity and salt exposure in coastal areas.
• Integration of multiple units in the same system: Opportunities and challenges of parallel coupling arc suppression coils in large networks.

Knowledge Sharing and Collaboration: Key to a Robust Energy Infrastructure

Events like this are crucial for strengthening collaboration between manufacturers, grid operators, and technical partners. Hans Følsgaard A/S plays a central role as a technical partner, bridging the gap between suppliers of high-tech components like Trench Group and the companies that implement these solutions in practice.

"Knowledge sharing is essential to ensure that we use the most efficient and reliable solutions in our power grid. The input we received today highlights the great value these professional events bring to the industry," says Lars Hoppe-Hagelskjær, Head of Powertech at Hans Følsgaard.

With the increasing electrification of society and a growing focus on grid stability, technological development and the correct implementation of arc suppression coils are becoming more important than ever. Hans Følsgaard A/S looks forward to continuing to facilitate this development in collaboration with market-leading manufacturers such as Trench Group.
