The author reviews the fundamentals of geographic information system (GIS) and global positioning system (GPS) technology and how the two can be integrated to improve the mapping and analysis of electrical distribution circuits. The primary benefits of integrating GPS data collection with a GIS are the establishment of an accurate coordinate reference and the rapid and cost-effective collection of geographic and attribute information about rural electric systems. When one is in the field with a GPS unit, a laptop personal computer should be connected to a serial port on the GPS receiver to act as a storage device for GPS readings and to collect attributes about electrical plant. The GPS positional and attribute data can be successfully overlaid on the detail base map in the GIS. The cumulative costs of integrating GPS with a GIS are not small, but are well-justified by the value produced in creating accurate, complete, and up-to-date geographic and attribute information about a utility's electrical plant. Future applications of GPS are considered.<>

The authors review various types of current-limiting fuses currently installed in distribution systems. The emphasis is on the safety and power-quality concerns addressed when selecting fuses for various applications. This includes a review of tests performed which indicate that the use of current-limiting fuses can reduce the probability of a disruptive failure of system equipment.<>

The meter minder is capable of storing up to 60 days of usage history for three on-site meters, which could all be electric meters, or one each of electric, gas, and water meters. Through its use, the utility gains knowledge of the electrical consumption, the quality of service, and the ability to connect/disconnect the service. The customers gain the ability to detect unwanted intrusion in their homes as well as 24-h monitoring of the household environment for fire, medical emergency, flooding, or freezing. The utility also gains by having a new revenue stream, from monitoring the add-on security system, to offset the expense of the meter-reading equipment. The customer also gains by receiving lower than market costs for the quality security service from the local electric utility.<>

In February 1991, the National Rural Electric Cooperative Association (NRECA) formed the Transmission and Distribution Engineering Committee (T&DEC). The purpose of T&DEC is to augment the Rural Electrification Administration's (REAs) ability to provide rural electric systems with technical information by: providing a mechanism whereby engineers from the rural electric systems can work together on items of common technical interest; establishing a national forum through which engineers from the rural electric systems can exchange technical information; providing a channel for rural electric systems to provide input to REA on field experience with items of material and equipment included in the REA List of Materials; and providing a method for rural electric systems to suggest to REA new or revised material or construction specifications, standards, guides, or other technical material.<>

Techniques are discussed which have proven useful in conducting power quality investigations. The discussion focuses on a few characteristics of power line disturbances which have proven helpful in localizing the source of power quality problems. One of the primary tasks of utility personnel responsible for customer's power quality concerns is to identify whether disturbances are generated within the customer's facility or on the transmission and distribution system. Advances in both instrumentation and troubleshooting methodology have made it possible to make these determinations with greater accuracy and less investment of time. Case studies illustrate how these techniques have been put into successful practice by utility power quality groups.<>

The author proposes a linking of common database information for use by all personal-computer programs, thus requiring the maintenance of only one database. The method requires the utility to study each of its database files and the individual components of these files. Decisions must be made on the necessity of each piece of information. A study of all existing file structures must be made. After completing all of these steps it is necessary to determine the type of database manager, operating system, and network. If multiple software vendors are involved, each vendor must be contacted to determine compatibility with planned systems. If there is no programmer on staff, one must be hired or a database consultant chosen. After these preliminaries are completed and the software written, the task of converting the database can be started. This is generally a manpower-intensive activity, but as time proceeds, the benefits become readily apparent.<>

The implementation of an automatic LTC control system that closes the loop between the autotransformer and the system energy control center is presented. The scheme uses the input of an optimal power flow (OPF) calculation on the energy management system computer to bias the centerband setpoint via a supervisory control and data acquisition (SCADA) of the voltage regulating relay installed on the transformers. Data regarding system parameters at the transformer are then sent back through SCADA to the energy management system computer for any further refinements for optimum power flow. The net effect of this control action is to flatten the transmission network voltage levels and rebalance the reactive flows to meet the load conditions and available reactive sources.<>

A historical perspective on electric system design changes that have evolved over the years is presented. These changes have provided more safety for the general public, but they also have created electrical contact problems that can affect livestock production. The steps an electric utility can take to reduce these voltages on grounded equipment are discussed, and how to deal with problems on both sides of the meter is considered. A flow chart has been developed for electricians or utility personnel in diagnosing stray voltage complaints.<>

On the basis of detailed power quality monitoring surveys, the authors present the power profiles of four different types of common farm operations to reveal the unique characteristics and variance in their power quality and to identify what electronic and electrical equipment is affected by the on-site electrical environment. Based on surveyed voltage disturbance characteristics, the origins and causes of on-site and utility disturbances are discussed. The power profiles of the various types of farm operations will provide a basis for mitigating actions by utilities and their rural industrial customers by enhancing their ability to identify the possible origins of power supply disturbances affecting the performance of electronic and electrical equipment. The power profiles also provide a guide for rural power line monitoring site surveys of the possible voltage disturbance characteristics that can occur at a specific farm site.<>
