This plan involves a surge a"ester installed at the service entrance and one or more plug-in suppressors installed within the premises, at the point of connection of a surge-sensitive appliance. Complementary tests were conducted at two laboratories to assess the compatibility of candidate devices with the needs of the utilities and the end-users. Basic, fundamental tests of protection performance and failure mode were performed for both suppressors and ~esters. Mechanical and environmental tests were performed on meter-base ~esters. In addition to obtaining data on test specimens, another outcome is the development of test protocols that can be used for systematic and consistent testing of other candidate devices.

The study addressed the technical and analytical challenges that must be addressed to enable high penetration levels of distributed renewable energy technologies. This RSI report focuses on the need for advanced distribution engineering analytical tools. High-penetration PV will change the way that distribution systems perform and provide both new capabilities and challenges for reliable, quality performance. The most fundamental change is the presence of generation on a system designed strictly to serve loads.

This paper puts into perspective the four most commonly discussed interface issues: harmonic content of the PV system output, power factor at which the system operates, voltage flicker potential attributed to cloud movement over the PV arrays and automatic

We have found that advanced power semiconductor devices, new circuit designs, and improved packaging techniques coupled with production volume can reduce PCS costs per kilowatt by a factor of four. PV array field modularity offers several options in central station PCS power and voltage ratings. PCS development potential for two size ranges, 50 to 500 kW and 1 to 10 MW, will be examined and compared.
