CIPCO's service territory has a rich history of damaging ice and wind storms. T2 ACSR conductors have been used on much of the construction in an effort to reduce or eliminate the damage. Many lessons have been learned about the use of T2 conductor, specifically in the areas of design, purchasing, associated hardware, installation, and long-term performance.","PeriodicalId":384151,"journal":{"name":"1997 Rural Electric Power Conference (Cat.

The electric distribution inspection data include, field observations on equipment conditions, amp and voltage measurements taken from capacitors, recloser, and voltage regulators and other information taken by field personnel when inspecting distribution facilities. The electric distribution area covers approximately 20000 square miles in Western Wisconsin with a combination of urban and rural customers. The field inspection data is collected and entered in field or office computers. The data is stored in a central server and is available to all employees. Reports are created after the inspection data is collected The reports have information that can be used to improve the reliability and performance of the electric distribution. The benefits of this method of reporting information are that the data is available for all users, work that needs to be done is shown on the reports, and the information can be quickly reviewed using the computer instead of sorting through paper records. This paper shows how reports can be created using a database program and how the reports can be used to improve the electric distribution system.","PeriodicalId":384151,"journal":{"name":"1997 Rural Electric Power Conference (Cat.

Proper lighting and ventilation is very important because it can provide the proper environment for many tasks including, office work, cleaning milking equipment, treatment of animals, health of animals. Energy conservation is of utmost concern in both lighting and ventilation applications. A good working environment is needed to increase working efficiency, comfort, and safety. Amounts of light will vary depending on the tasks that are being performed in the various areas of the milking or housing facility.","PeriodicalId":384151,"journal":{"name":"1997 Rural Electric Power Conference (Cat.

In order to make the comparison, a distribution engineer needs to have the analysis tools to perform the necessary reliability studies. For purposes of this paper the reliability studies are limited to the calculation of the annual \"outage rate\" and associated \"restoration time\" for a typical customer on a radial distribution feeder. The paper develops the background and theory for computing these reliability indices. The method can be applied to demonstrate how different devices and/or feeder configurations affect the average customer on a specific feeder. The equations are derived in such a manner as to facilitate their use in computational software packages.","PeriodicalId":384151,"journal":{"name":"1997 Rural Electric Power Conference (Cat.

Overhead primary comprises 69% or 3178 circuit miles of CCEC's distribution system. The vast majority of CCEC's overhead primary distribution system was constructed during the 1930s and 1940s, which indicates the system is reaching 50+ years of age. Underground primary cable comprises the remaining 31% or 1436 circuit miles of CCEC's distribution system. Installation of underground primary cable was very prevalent in the 1960s and 1970s at CCEC. However, due to a continuing history of premature cable failures, underground primary cable is now being replaced significantly sooner than the cable's anticipated life expectancy. This paper outlines the systematic approach utilized by Cass County Electric Cooperative to begin replacing its aging overhead and prematurely failing underground primary distribution systems.","PeriodicalId":384151,"journal":{"name":"1997 Rural Electric Power Conference (Cat.

This article focuses on the newly discovered and documented feasibility of using FR rainwear in high fault current switching applications. This article includes data and a comparison of 7 popular rainsuits materials in their performance under electrical arc conditions. Some of these rainsuits have been shown by mannequin testing to withstand arcs up to 30000 Amps 15 cycles without sustained fire or ignition of clothing covered. Using rainwear as switching jackets could allow \"double duty\" use of rainsuits in plants and on line trucks. Further Neoprene/Nomex(R) and some PYC/Nomex(R)/Kevlar(R) rainsuits have, in testing, proven more protective than woven Nomex(R) \"switching jackets\" costing substantially more.","PeriodicalId":384151,"journal":{"name":"1997 Rural Electric Power Conference (Cat.
