Biography

Optimizing Silicone Rubber-Based Housing Materials for HV Composite Insulators in Outdoor Applications

Dr. Baer received a Diploma in Electrical Engineering from the University of Applied Sciences Zittau/Görlitz and a Dr.-Ing. Degree from the Technical University of Munich. She has worked for the past five years as Development Engineer for polymeric insulators and sets and Head of Material Development for composites. She contributes to CIGRE Working Groups related to material properties of polymeric materials for HV applications and is also active in IEC TC 112 & TC 36.

The trend toward tailor-made composite insulator solutions is pushing further development of their housing materials and designs. This is triggered by strategic moves such as UHV, expansion of HVDC, new requirements in utility specifications and compact lines. These trends are also reflected in refinement of existing test methods to verify quality as well new tests to better transfer service experience into the design stage. This presentation focuses on trends in new HTV silicone rubbers and gives examples of developments in their formulations to meet more demanding requirements based on service experience as well as the new test methods.
