Seismic Qualification of Disconnect Switches
Scope of Research
- To qualify standard 230 kV Disconnect Switches with various porcelain insulators to Moderate and High Performance Seismic Level (based on IEEE 693 protocol)
- Characterize and model porcelain and switch
- Develop methodology that would allow replacement of various porcelain posts without re-testing the entire switch
- Recommend modifying IEEE 693 standard based on test design and testing procedures
Test series held during the month of April, 2005.
Testing on the weeks of March 13-17, 2006 and March 27-31, 2006.
The study is sponsored by MCEER (Multidisciplinary Center for Earthquake Engineering Research),
by EPRI (Electric Power Research Institute) and by EUC (Electrical Utility Consortium).
