The success of utilities as they proceed into the deregulated environment will depend to a large part on their ability to integrate information systems across their organization. Mapping is emerging as a central component of utilities' information infrastructure because of the association between data and communicative graphic images provided by geographic information systems (GIS). Another category of utility automation is field design tools. They share some of the compelling usefulness of the mapping system while increasing the productivity of staking personnel and the design/build process. Early field design packages were computer versions of paper staking sheets, but current products are more sophisticated, providing process improvements in mapping, accounting, and other utility departments. Field design products that include work order management functions can interface with other systems to more effectively gather and distribute information. This paper makes recommendations to utilities that are considering implementing an automated field design system.","PeriodicalId":364482,"journal":{"name":"1999 Rural Electric Power Conference (Cat.

The power line is 9 miles in length and connects rural distribution substations. The construction also allowed for a voltage upgrade from 34.5 kV to 69 kV. The steel alternative to wood was initially considered as a means of extending the life of conventional southern yellow pine (SYP) poles. A closer examination of the physical characteristics revealed advantages in overall strength, buckling, and bending. The steel poles consisted of galvanized tubular steel, classes 1, 2 and 3, and lengths from 55 ft to 70 ft. The 2 piece tapered poles are slip fit (overlap approx. 24-in) together above ground line. The 12.5 kV underbuild utilizes fiberglass cross arms and standoffs. Conventional pole bands were replaced with guying tees, thimble eyes and eye bolts for both overhead and down guys respectively. The steel pole eliminated the need for the normal TM-9X shield wire ground and reduced framing labor and material cost. The overall result was a stronger and lower initial cost power line. The minimal inconvenience of setting a 2-piece pole was more than offset by the labor saved in transporting and framing. During 1998 grounding tests were conducted on steel poles with and without ground rods. These tests revealed that the steel poles were effectively grounded whether with or without a parallel ground rod. Rock fill around the poles in place of soil did not greatly reduce the grounding resistance to earth.","PeriodicalId":364482,"journal":{"name":"1999 Rural Electric Power Conference (Cat.

While most companies are considering NMR for strategic reasons, they must also prove the cost effectiveness of such a system. In 1995, AmerenUE (then Union Electric) made a decision to install the CellNet Data Systems NMR network in its metropolitan service territory. This decision was predicated on the perceived benefits of NMR and the company's desire to position itself for successful operation in the competitive world. Since that decision was made, over 800000 automated meters (including supporting infrastructure and information handling systems) have been installed and operated. The company's experience with NMR during over three years has substantiated the originally perceived benefits of system deployment. After a comprehensive review of NMR performance and a detailed evaluation of relevant economic factors, AmerenUE made the decision to extend automated meter reading into its rural service territories starting in 1998. This paper presents the bases for that decision. Economic benefits and technical considerations of implementing the system in a low customer-density setting are addressed. Extended applications, including outage detection, transformer load management and current diversion detection are also discussed.","PeriodicalId":364482,"journal":{"name":"1999 Rural Electric Power Conference (Cat.
