One of the key reasons for improvement has been the advent, development and use of pulse width modulated (PWM) drives utilizing faster switching devices, primarily insulated gate bipolar transistors (IGBTs). As with many other developments, improvements in some areas may cause problems in others. An increased bearing failure rate in motors is one of the negative effects of these types of drives. To mitigate bearing current damage in motors, as well as in loads and other auxiliary equipment attached to the motor shaft, it is important to understand how these currents are generated. In addition to theoretical explanations, actual field cases and solutions are reviewed.","PeriodicalId":360061,"journal":{"name":"Conference Record of 1998 Annual Pulp and Paper Industry Technical Conference (Cat.

The good news is that advancing applications of electronics are making more accurate control and monitoring of EHT circuits more affordable, and for the sake of this article, able to meet the new code requirements without using specialty circuit breakers.","PeriodicalId":360061,"journal":{"name":"Conference Record of 1998 Annual Pulp and Paper Industry Technical Conference (Cat.

Whether for raw materials, MRO goods, engineering design services, or capital equipment, they are developing and implementing supplier partnerships, many of which take on the name and structure of a strategic alliance. Increasingly, top management at large manufacturers and engineer/constructors have come to believe that reducing their supplier base, and thereby increasing the relevance of the relationship between themselves and the remaining suppliers, will achieve their goals of lowering overall costs while improving service and quality. Encouraged by consultants and studies at a number of business schools, company executives have declared that their purchasing departments will pursue strategic alliances as another element in a growing effort to change \"business as usual\" mentalities within their companies. This paper reviews the rationale for the formation of a strategic alliance between a major industrial manufacturer and a supplier of engineered electrical products. It focuses on the internal processes that were developed to change the culture within both organizations, and the methods of implementation which help insure success in meeting the goal of reducing the total cost of ownership.","PeriodicalId":360061,"journal":{"name":"Conference Record of 1998 Annual Pulp and Paper Industry Technical Conference (Cat.

This paper is a case study of the development of a method to provide electrical and other documents to the maintenance and engineering work forces at the West Tacoma Mill. The intent is to show the steps taken over time which, although still evolving, are resulting in complete electronic availability of electrical and instrumentation and other engineering documentation. Development of a maintenance document system for the electrical and instrument group at this mill was the result of a long strategy of improvement, much like the pieces of a puzzle that finally comes together. Following steady evolution towards modern control systems has allowed the mill to develop a totally integrated control and information system.","PeriodicalId":360061,"journal":{"name":"Conference Record of 1998 Annual Pulp and Paper Industry Technical Conference (Cat.

Those who analyze the data and prepare work orders for maintenance and repair know why they have prepared the orders, but those involved in the actual maintenance of the machinery, often know little more than which component to replace. By implementing an easy-to-use, accurate system of both machinery condition data collection and analysis, and by involving all maintenance personnel in the process, plant operation can become efficient and cost-effective. Personnel are educated as to the cause and extent of the damage, and learn how essential it is to pinpoint potential problems before they occur. By taking this proactive approach, a company can save millions of dollars by avoiding costly damage, unscheduled shutdowns, lost man-hours and missed project deadlines. This paper describes how to practically implement a cost effective predictive maintenance program, discussing what to do, what not to do, case histories, and the benefits and results achieved.","PeriodicalId":360061,"journal":{"name":"Conference Record of 1998 Annual Pulp and Paper Industry Technical Conference (Cat.

This information made it possible to observe line-to-ground faults, sudden changes in phase currents and oscillations in phase voltage or current. Four-quadrant metering and accurate time-stamping of power quality events provided the information needed to determine the sequence of events in a forensic analysis of the disturbance leading to the damage.","PeriodicalId":360061,"journal":{"name":"Conference Record of 1998 Annual Pulp and Paper Industry Technical Conference (Cat.
