The state of the art in power monitoring technology in the pulp and paper industry is described. The value of two-wire communications and how it can be linked into computers, programmable logic controllers, and distributed control systems are explored. Application examples illustrate the cost and capability benefits of collecting data from an integrated network of electronic sensors as compared with traditional electrical instrumentation wired to input/output modules.<>

The selection, application, and performance of room-temperature-vulcanizing (RTV) silicone rubber coatings for the maintenance of electrical substation insulators are described. The ability of silicone rubber coatings to suppress leakage current, thereby eliminating the cause of electrical power interruptions to the plant, is discussed. Coating life expectancy is discussed in terms of the pollution conditions, the frequency of maintenance cleaning, and the formulation of the RTV silicone rubber coating system.<>

Starting large refiner motors in the paper industry has become a more complex problem due to steadily increasing motor size, and more stringent requirements on power quality in urban areas. Several possible starting methods are presented, and the solution chosen for a project is discussed in detail, showing how the chosen method met the process criteria, while keeping power line disturbances within guidelines of the power utility involved. The advantages and disadvantages of each method are explained, and a relative capital cost is presented. The reader will gain an understanding of the considerations necessary to select an optimum starting method.<>

The complex nature of the lime calcining process with its long time delays, variable feed characteristics, changing operating conditions and nonlinear chemical and thermal reaction rates makes the rotary lime kiln difficult to operate. A lime kiln automation system that combines an expert system with adaptive loop controllers to automate kiln operation and provide significant kiln performance improvements is described.<>

Pulse-width modulation (PWM) inverters provide many benefits to their users, including improved control of processes, reduced energy consumption, and expanded diagnostics. Despite these benefits, PWM inverters should be applied with special consideration for low-voltage induction motor operation. Some of the known, possible adverse effects PWM inverters cause for low-voltage induction motors and the impact these effects have on the given application are highlighted. These effects include increased heating, high peak voltages, and increased audible noise. This work is intended for those who are applying PWM inverter-fed low voltage induction motors, not those designing them.<>

The development of synchronizing equipment and of the electrical connections used for synchronizing and connecting two independent power systems is reviewed. A number of considerations are given that should be studied for planning the installation of automatic synchronizing to replace existing manual systems. A centralized automatic synchronizing system is presented as installed in one paper mill power house. The system includes a master manual-automatic synchronizing panel and a remote synchronizing panel. The system is used to synchronize and close 16 generator, utility, and bus connecting breakers. Diagrams of the basic electrical connections are shown as well as pictures of the synchronizing panels.<>

An overview of environmental legislation affecting manufacturing businesses and their customers is provided. Special emphasis is given to current and future environmental issues which will affect wire and cable manufacturers and the resultant effects on processes and materials, costs of compliance, and products which will have to be modified. The implications of the changing regulations on end users are discussed in terms of product disposal and recycling, packaging, continuity of supply, and effects of product changes. It is concluded that cooperative and user/manufacturer programs will smooth the pathway into the future.<>
