It was determined that if a used steam turbine generator could be installed at the plant, this would be a viable way to reduce manufacturing costs. The unit would displace purchased electrical energy with \"in house\" generation during times that the plant could produce the energy for less than it would be charged by the electric utility. During these times, the unit would be operated in a mode such that the electrical energy flowing into the plant through the utility intertie would be kept to a minimum (tie line control mode). During other times of the year, providing that it was economical, the plant could sell electrical energy to the utility. Once the unit was purchased and the degree of reconditioning and repairs to the turbine and the generator had been determined, the next major decision was which of the auxiliary systems could be re-used. This paper covers the process involved in evaluating whether or not to reuse the generator's original compound excitation system and if replaced, the type of excitation system that should be installed, compound or potential bus fed type. Discussed are the issues encountered during the evaluation process, the expectations desired, the decisions made and the outcome achieved as a result of the final decision to replace the existing compound excitation system with a potential bus fed excitation system.","PeriodicalId":189773,"journal":{"name":"Conference Record of 2004 Annual Pulp and Paper Industry Technical Conference (IEEE Cat.

Historically, there has not been a lot of information available to service centers to use as a comprehensive guide to electric motor repair. End users of machinery always look for a resource, a document upon which to base our repairs. The EASA Standard ANSI/EASA AR100-2001 Recommended Practice for the Repair of Rotating Electrical Apparatus provides important guidelines; however, it does not go into great detail. Last year, EASA made available the publication, a detailed guideline, titled \"Mechanical Repair Fundamentals\". The book breaks down the motor into its mechanical components and offers specific repair procedures and tips for each component of the motor system. IEEE Standards are referenced throughout the text. This paper gives an overview of \"Mechanical Repair Fundamentals\" and how it is structured. It can be used by the service center for reference and by the end user to help them understand how their motors are repaired. The value to the end user is that he/she can direct the motor repair facility to specific, acceptable repair practices to be incorporated into the repair of specific motors, and also note any exceptions to a common repair practice.","PeriodicalId":189773,"journal":{"name":"Conference Record of 2004 Annual Pulp and Paper Industry Technical Conference (IEEE Cat.

Interrupting capacity and short-time current ratings define different circuit breaker performance characteristics. The short-time rating is used by the engineer to determine the ability of the circuit breaker to protect itself and other devices and to coordinate with other circuit breakers so the system will trip selectively. While interrupting capacity rating levels of circuit breakers are somewhat consistent throughout the electrical industry, short-time current rating levels are often inconsistent. It is important to understand the performance characteristics of the specific device in order to apply it properly. The present emphasis on higher interrupting ratings, current limiting, and series ratings has impacted the short-time current ratings of circuit breakers. This paper examines the interrupting capacity and short-time current ratings of molded-case circuit breakers, insulated-case circuit breakers, and low-voltage power circuit breakers and their effect on time-current coordination. It reviews resistive and reactive X/R ratios and explains the short-time current and instantaneous trip characteristics of microprocessor-based trip units. A good understanding of interrupting capacity and short-time current ratings allows the electrical engineer to make a proper comparison of various circuit breaker designs.","PeriodicalId":189773,"journal":{"name":"Conference Record of 2004 Annual Pulp and Paper Industry Technical Conference (IEEE Cat.
