  • This report presents the results of a program to develop compact capacitor banks and harmonic filters for transmission voltages with an installed cost equivalent to air insulated capacitor banks. The objective of this work was to develop, design, build, install, and field test such compact capacitor banks. For demonstration purposes, a single phase 362-kV shunt bank and a three phase 145-kV 11th harmonic filter were to be designed, constructed, and field tested.
  • Polypropylene and polyolefin resins were characterized and processed into capacitor films. New capacitor films were developed--a post oriented processed, two layer polypropylene film and upgraded polyolefin film. Criteria for judging film quality was developed. Field life data was verified with paper/polypropylene capacitors on the Maxwell Rep Rate Facility. All polypropylene film capacitors were developed with lifetimes in excess of 10/sup 7/ discharges at energy densities for the finished capacitor of 18.3 J/lb and projected to > 20 J/lb.
  • This report describes the results of a project to determine whether it is feasible to make a liquid-free 200 kVAR, 7200 Vac power factor correction capacitor. After evaluating many solid and gaseous candidate systems, the combination of vapor deposited electrodes on polypropylene sheet dielectric, encapsulated in polyurethane resin was selected. Cell capacitors were used for the initial screening. Next a series of mid size model capacitors were built to evaluate the bushing and the terminal-to-case insulation. Capacitors with vapor deposited electrodes can sometimes generate enough gas at end of life to rupture the case. While no liquid will emerge frommore » a dry capacitor in this situation, there can be a brief jet of flame from an arc. To avoid this, a presence actuated protector device was developed to prevent excess pressure buildup at time of failure. Full size capacitors passed extended life tests, fault tests and radio noise tests. Finally, field trials were run at five widely dispersed installations. The field trials were successful. The present projected cost of dry power capacitors is significantly greater than their liquid counterparts. Future changes in environmental requirements, together with further technical development, may change this situation.« less
