Excerpt from Calibration of Voltage Transformers and High-Voltage Capacitors at Nist In the past nist had used a comparative null method to calibrate voltage transformers. The un known transformer was compared to a nist refer ence transformer using a voltage comparator consisting of a variable resistive divider and a mu tual inductor. Reference transformers were avail able with ratios ranging from up to Measurement uncertainties in the comparison of the unknown transformer with the reference trans former were to.ol% for ratio and t0.3 minutes for phase angle. The ratio and phase angle of the reference transformers were known to about the same accuracy. There are several disadvantages to this approach. Since the comparator has a limited range, several reference transformers must be available to cover the anticipated users' needs. The ratio and phase angles of each one of these trans formers must be carefully determined over the secondary voltage range of interest. These trans formers then have to be rechecked at regular inter vals to determine if the ratios and phase angles have changed. If a direct measurement method were available that was sufficiently accurate and straightforward to make the calibration of these reference trans formers a simple task, then that method could be used to measure the client's transformer directly. At nist, the direct null method in use origi nally involved balancing the secondary of the ref erence transformer against the output of a resistive divider used in conjunction with a variable mutual inductor to provide phase angle balance. Such a measurement was difficult because the resistive di vider ratio changed with heating. Since the late 19605 a direct null method has been available that is straightforward and accurate and is now used at nist in place of comparative methods us ing reference transformers. Capacitors are invariably measured by balancing the unknown capacitor against a known standard using some type of bridge arrangement. There are a variety of such bridges described in the literature The one most used in high-voltage applications in the last 60 years is the Schering bridge (fig. The two high-voltage arms of this bridge consist of the standard and unknown capacitors. The two low voltage arms are resistors (one has a parallel capacitor for phase angle balance).

This second edition of An Introduction to Predictive Maintenance helps plant, process, maintenance and reliability managers and engineers to develop and implement a comprehensive maintenance management program, providing proven strategies for regularly monitoring critical process equipment and systems, predicting machine failures, and scheduling maintenance accordingly. Since the publication of the first edition in 1990, there have been many changes in both technology and methodology, including financial implications, the role of a maintenance organization, predictive maintenance techniques, various analyses, and maintenance of the program itself. This revision includes a complete update of the applicable chapters from the first edition as well as six additional chapters outlining the most recent information available. Having already been implemented and maintained successfully in hundreds of manufacturing and process plants worldwide, the practices detailed in this second edition of An Introduction to Predictive Maintenance will save plants and corporations, as well as U.S. industry as a whole, billions of dollars by minimizing unexpected equipment failures and its resultant high maintenance cost while increasing productivity. A comprehensive introduction to a system of monitoring critical industrial equipment Optimize the availability of process machinery and greatly reduce the cost of maintenance Provides the means to improve product quality, productivity and profitability of manufacturing and production plants
