Gas-insulated and air-insulated switchgear (GIS/AIS) have been fundamental to the reliable distribution and transmission of energy across the globe for numerous years. Despite their critical role, these systems frequently overlook the necessary maintenance schedules, resulting in unforeseen outages. With energy demand projected to surge by 50% by the year 2040, coupled with the increasing intricacy of electrical grids due to extreme weather events, cybersecurity threats, and the ongoing energy transition, the importance of condition-based maintenance has never been greater.

High voltage assets play a critical role in powering factories, transportation systems, hospitals, offices, data centers, and homes. Any failure can have severe consequences. By following OEM guidelines and implementing proactive time- and condition-based maintenance, we maximize equipment performance and longevity, combat natural aging, and ensure smooth operations through timely part replacements and the expertise of local professionals.

Our initial on-site investigation involves a thorough assessment of the issue at hand, allowing us to develop tailored repair solutions. Our repairs are carried out by expert field service personnel and include high-quality parts and materials.

Additionally, our OEM workshops are equipped to address failure analysis and provide comprehensive repair services. Trust us to deliver effective and reliable solutions to meet your repair needs.

Our service contracts provide premier support for your assets, reducing operational risks and enhancing efficiency. Our Service Level Agreements guarantee reliability and profitability, offering customized solutions like scheduled maintenance, remote services, and extended-term programs.

With our Operation and Maintenance (O&M) service level, we assume full operational responsibility, thereby reducing your risk.

Opt for Siemens Energy for superior power grid reliability, efficiency, and assurance.

Circuit breaker replacement is necessary to ensure the continued safe and reliable operation of electrical systems. Over time, circuit breakers can deteriorate due to factors such as wear and tear, aging, or changes in electrical load. Replacement is essential to mitigate the risk of electrical faults, equipment damage, and potential safety hazards. Upgrading to modern, more efficient circuit breakers can also improve system performance and reliability.

Retrofit for switchgear and circuit breakers is crucial to ensure the performance and safety of your electrical infrastructure. By modernizing existing systems with new technologies, you can enhance efficiency, reduce downtime, and extend the lifespan of your equipment. Retrofit helps you meet current standards and provides a cost-effective solution to upgrade your switchgear without needing to replace the entire system. Invest in the future of your electrical systems and benefit from improved reliability and safety.

Power transmission service has masterfully completed Latin America's largest retrofit of electrical infrastructure, modernizing 40 substations and spanning over 2,500km with voltage levels up to 500kV.

Our expert teams executed the replacement of 240 circuit-breakers and 731 disconnectors with precision, working during off-peak hours with temporary power solutions to ensure seamless service continuity.

The retrofit boosted facility reliability, slashed operational costs, and improved operational metrics, reaffirming our commitment to delivering excellent service and meeting societal energy demands.

This success story showcases Siemens Energy's dedication to setting new standards in energy infrastructure, driving progress, and energizing the future of Latin America with reliable and efficient power solutions.
