The new revision of IEEE Standard 519 became official in 1993. The new standard has been greatly expanded and includes additional stringent limits on individual and total current harmonic distortion in addition to the voltage distortion and line notching limits already included in IEEE Standard 519-1981. A modern industrial power system may include variable frequency drive (VFD) loads at several locations. The new standard requires a careful "global" harmonic analysis of the entire power system to specify the right type of VFD technology for the application and ensures compliance with the standard. This paper presents a general methodology for computing voltage and current distortion in accordance with IEEE 519-1992. The paper presents a case study that further emphasizes the importance of harmonic analysis. The impact of the new standard on the state-of-the-art of VFD technology is discussed.<>

During 1992, Boise Cascade's white paper mill in Jackson, Alabama, USA successfully implemented the ISO 9002 quality system and received registration under the international organization for standardization. This paper reviews the process the mill followed with emphasis on the efforts of the maintenance department's electrical and instrument (E&I) group to develop a personal computer (PC) based instrument tracking system for National Institute of Standards and Technology (NIST) traceable process instrument calibrations. The overall issues discussed are: The ISO 9000 series quality system; developing and implementing an ISO quality system for process instrumentation; preparing for and experiencing a registration audit; and maintaining a compliant ISO quality system.<>

Variable speed AC drives are finding their way into all types of industrial and commercial power system applications. Their application to the load (motor) generally is reasonably well selected-at least within heavy industry. However, there are many line (source) design parameters frequently overlooked. This paper presents some of the major (and not so major) areas of concern which frequently result in serious performance or power supply quality problems. Finally, basic design guidelines are given to greatly minimize system problems-especially as newer technologies are intermixed with old.<>

Motor problems usually cause a crisis, and are quite aggravating, especially if the problem could have been prevented. The keys to successful motor operation include: a quality motor; understanding of the application; choice of the proper type of motor for the application; proper installation-mounting, coupling, surroundings-for the motor; and proper maintenance of the motor. Certain problems seem to reoccur more frequently than others. The authors describe how many problems may be avoided, if the application and environment are understood, while others may be caused by a changing environment in which the motor operates, and, of course, some are due to the motor itself.<>

The occurrence of multiple ground fault events in a low resistance grounded 13.8 kV power system may have an unexpected cause. This situation serves to illustrate that short circuit and load flow analyses alone are becoming increasingly inadequate as the sole means used to insure proper system operation and to minimize disruptions in three phase power systems employing capacitor banks.<>

An expert system has been developed which helps maintenance personnel diagnose the condition of rotor and stator windings in motors and turbine generators rated 2300 V and above. The expert system, called MICAA, uses an approach which has been found to be effective for diagnosing medical problems, and which has proven to be a much better medium than a printed handbook for diagnostic applications. The user interacts with the program to input machine nameplate information, operating status, and any past test data that is available. In addition, the program suggests tests which may be useful, as well as guiding maintenance personnel on what to look for in visual inspections of the machine. The expert system stores and correlates all this information, calculates the overall condition of both the stator and rotor windings, and identifies the most likely specific causes of any deterioration. The latter is very useful for determining what maintenance or operating changes are needed to extend winding life. In addition to its diagnostic capability, the program's comprehensive technical help and the ability to store test data in a permanent database have also been of benefit to users. The expert system is now being used by over 200 maintenance personnel primarily in power utility companies in the United States. This paper first describes the reason for the development of an expert system in this area, and then describes its application as a preventive maintenance tool for motor and generator condition assessment.<>

Variable frequency AC (VFAC) sectional drives are now a viable option to the conventional DC drive. The high-tech electronics industry of power devices, integrated circuitry, personal computers and software have developed an AC drive using vector control which has similar features to a DC drive. Although enthusiastic consideration is seen offshore, the North American market seems to be very slow in recognizing its merits. This paper has been written to share one experience in the selection, installation and operation of an AC sectional drive. It is more of a practical approach as there are many papers available that discuss the technical features. Since the equipment is driving a research pilot coating machine, there are obviously some details omitted which the company felt were confidential but these do not impact on the intent of the paper.<>

The author describes how the choice of which type of power and control cable raceway to utilize in the pulp and paper industry is usually based on several factors. Tray systems provide an economical means of providing a stable raceway for power and control wiring. They can be utilized to provide the requirements of most projects. Conduit can achieve the same results at a higher cost in large cable installations. For smaller projects where there are not as many wires then the conduit system is the most economical. Conduit has the distinct advantage of keeping in compliance with the NEC. Once the system has been installed, the possibility of overfilling the system is small. The tray system is a challenge to keep in compliance with the NEC.<>

Energy consumption by pulp and paper mills in North America represents a large percentage of the total electrical energy consumption of industrial plants. There are several new technologies available to make it possible to save energy. Current information indicates that few businesses are taking advantage of these technology advancements. With the addition of electric utility rebates, businesses have an added incentive to update facilities in order to be more efficient and cost effective. This document updates the user with the different rebate programs available, the type of equipment available for rebates, and the basic methods which need to be followed to obtain the rebates.<>
