Power surges from a bolt of lightning on a Sunday led to a widespread power disruption on a busy highway.

In the heart of Germany, the Pforzheim city area, along with Keltern and Ispringen, experienced a power outage on Sunday morning. The cause of this outage was a lightning strike on a 110-kilovolt overhead power line, affecting both Netze BW and Stadtwerke Pforzheim (SWP) networks.

Stadtwerke Pforzheim, the city's utility company, announced the power outage in a statement and on their website. During the outage, quick clarification was possible due to calls received by the SWP on-call service.

Automatic safety mechanisms, common in power outage situations, were activated. These mechanisms include immediate power shutdowns to prevent equipment damage or hazards, backup battery-operated systems to maintain critical functions, power outage alarms and notifications, and automatic switching to backup power sources like generators or battery storage systems.

Specialized systems might also incorporate sensor-based monitoring to ensure safety, such as pressure or motion sensors detecting operator engagement and triggering shutdown if no activity is detected. Remote control capabilities allowing operators to reboot or manage equipment remotely during an outage are also part of these safety measures.

In municipal or large-area outages, operators rely on monitoring and alert systems to prepare and respond efficiently, aiding rapid restoration and safety.

After all transformer stations were brought back online, SWP was able to restore power to the grid. Some SWP employees who were not on call supported their colleagues on site during the power outage.

It is important to note that this article does not provide information about the duration of the power outage. No current phone or contact information for Stadtwerke Pforzheim is provided in this article. The affected high-voltage line runs between the Birkenfeld transformer station and the SWP transformer station in the Enzwerk. The power outage also affected the network areas of Keltern and Ispringen, in addition to Pforzheim.

This combination of safeguards was likely at work during the Pforzheim incident to minimize risks to people and infrastructure. Detailed public information specific to Pforzheim’s mechanisms is not explicitly provided in the current search results. The mechanisms described are generally standard industry practice for power outage safety.
