Project UHV.-Construction and Technical Plan

A description is given of the facilities at Project UHV for the study of EHV and UHV ac transmission problems up to 1500 kV. These facilities include a 1500/?3 kV, single-phase autotransformer, a special 900-kV lightning arrester, and much associated UHV and EHV measuring equipment. Special stringing procedures are employed to string overhead test lines, and special test cages yield the corona characteristics of bundle conductors. Research is in progress on 1000 to 1500 kV transmission lines.
