Their fault-free operation is essential for a reliable power supply, but even the best technology can be significantly affected by aging and wear. That is why we offer a full range of services from reviews and consulting, planned maintenance, and inspections, repair services, and spare parts to modernizations and extensions. In addition to Siemens products, we also service Allis-Chalmers, Siemens-Allis, VA Tech, Westinghouse, Merlin Gerin, Elin, Peebles, Ferranti Packard, and Trafo-Union products.

Highlight services for long lasting high-voltage products

Siemens offers you such a comprehensive service portfolio for your high-voltage products that it is worth your while to take a closer look at some of our many offerings.

Strategic spare parts program for GIS and AIS

Operational availability is a key element for the effective application of high-voltage switchgear. If a breakdown occurs, there is an urgent need for the proper spare parts. That is why Siemens offers you a strategic spare parts program for your high-voltage switchgear. Our experienced experts give recommendations based on detailed assessments and analysis via standardized inspections. We offer five different interconnected modules, but you can choose any combination or a single module according to your individual needs.

  • Module 1: Installed base alignment
  • ­Module 2: Inspection of customer spare parts storage
  • ­Module 3: Spare parts recommendation
  • ­Module 4: Condition assessment of equipment
  • Module 5: Strategic spares solution

Gas density monitoring for gas isolated switchgears

Recent European and North American legislation has focused on greenhouse gases such as SF6, with the target of reducing emissions to 0.5% per annum. As a result, gas density monitoring is essential to improve leakage visibility, notwithstanding the superior performance of modern gas isolated switchgear (GIS). Siemens Assetguard GDM takes care of the actual SF6 gas condition and support managing a more dynamic and extensive network where conventional routine inspections are not viable. Some example features are:

  • ­Single line diagram view for easy localization
  • ­Gas density measurement with high accuracy, recognition of trends and prediction of intervention dates
  • ­Overall SF6 gas inventory
  • Data storage for expert analysis
  • Alarm forwarding to Siemens Customer Support Center.
